C++ Programming Homework Solutions

C++ is a programming language that evolved from C language is a complex subject but is compatible with many. It leads to syntactical choices. Our online C++ homework help service knows the complexities of the language and can deal with any problems you may have. The C code is very close to a portable version of assembly language, and C++ designed to perform expensive operations. Later versions of C++ added exceptions, which do lead to code bloat and less efficient code in addition to templates, which can lead to code bloat if not used carefully.
C++ programming homework solution
C++ offers overloaded operators, which means that you can implement your language in C++, with variables that act as non-standard types with a syntax that uses operators to call functions. One use for operators is overloading << and >> to perform input and output, since included in the standard library. We offer the best website for C++ homework assignments and can solve any problems on the same. For C++ homework help contact us for a quote.

C++ Programming Assignment Help
If you are looking for C++ assignment help, whether it is a simple demonstration of object orientated code, or writing a templated data structure, or working with complex 3D graphics using OpenGL, then you've come to the right place. One of the best C++ features is the ability to generate efficient code. C++ is a compiled language, so it runs directly rather than running in a virtual machine. Allocating memory means that it is more likely to cause a cache miss, so C++ allows you to allocate class objects on the stack rather than just on the heap.
Virtual methods use a pointer to control the invocation of a call, this is much simpler than defining a function pointer that you would need to do in C to achieve the same ends, and it can even avoid the indirect call if it knows the concrete type. So let us know if you need us to provide C++ homework assignments to guide you.

Operator Overloading in C++

C++ is the most complicated programming language in widespread use, but this is because it is basically multiple languages in one. You can use C code almost completely unmodified, you can write code that is similar to Java or you can use it to its full and implement your own language inside C++. It was designed to be efficient, and unless you need to use a feature then it would not cost you compared with equivalent C code. If you use virtual methods then it will be slightly slower, but if you don’t need them for a class there is no cost. C++ provides access protection (private and public methods and variables) which is similar to Java but a slightly different syntax, but also offers features not supported in Java. One of the features is const which enables you to say a method will not modify any fields inside the object, and the other main one is operator overloading which enables you to write much more readable code.

Structured binding in C++

A structured binding is the allonym of an available object (like a reference), but its type should not be a reference one (unlike a reference). In detail, structured bindings allow declaring several variables that are initialized from a structure.
Structured binding is a recent programming capability, which is added in C++17 to create clean applications. Indeed, C++17 programming language allows binding the determined names to initialize elements (sub-objects) for more understandability.
The general syntax of structured binding in C++ is:
  • auto references-operator(optional)[id-list](expression);
In this statement, the id-list demonstrates the list of variables separated by the comma operator. The expression is a non-union class type (array) that does not contain the comma.

String in C++

In C++ programming language, a stream of characters (bytes)is defined as String(an object of the std:: string class), allowing to enter, modify, and store single-byte characters. Unlike character arrays that pre-allocate memory statically, strings are assigned demand-based memory dynamically at run-time to deal with resource waste. Besides, character arrays do not provide several predefined functions to manage strings. However, string class offers a complete set of functions to performs operations on characters. Some of the most common string functions in C++ are:
1. Input functions
  • getline()tosavea string
  • pop_back()to eliminate the last character of a string
  • push_back()to add a character at a string
2. Capacity functions
  • capacity()to demonstrate allocated capacity to a string
  • length()to show the length of the string
  • resize() to manipulate the size of a string
3. Manipulating functions
  • copy()to copy a string in a character array
  • swap()to swap a string with another

Proxy in C++

A proxy refers to a structural template. It provides an opportunity for the customers to exploit another object instead of the leading service one, so that:
  • The customers send their requests to the proxy.
  • The proxy performs some tasks on customers’ requests, such as cache or access control.
  • The modified requests are transferred to the service objects.
Proxies are still useful in some C++ applications, which require set up extra behaviors to an object without the client’s code modification. Proxy patterns must refer to a service object when they are not a subclass of it. To use the proxy in the C++ programming language:
  • Design a covering class (it maintains a pointer to the leading class).
  • Set the initialized value of the pointer to null.
When a request arrives, the leading object is initialized, and the request is appointed.

Is It possible to Build a Virtual Constructor in C++?

Since C++ is a statically-typed programming language, the programmers cannot build a virtual class constructor for polymorphic object creation. Indeed, the C++ compiler must know the class type for object creation (specifying the object type is a compile-time task). Thus, the compiler shows an error when the programmers build virtual constructors because only the constructor declaration is allowed in C++.
In real-world applications, object creation and its type are firmly intertwined. The purpose of the virtual constructor is to separate the object creation from its type. It works when a base class pointer is to a derived class object. In C++, the constructor cannot be virtual because when a class constructor is performed, there is no virtual table in the memory, demonstrating no virtual pointer is defined. Therefore, the constructor in the C++ programming language should be non-virtual.

Function Analysis (Asymptotic Analysis)

Function analysis (asymptotic analysis of the function)is defined as the program's mathematical limitation run-time performance. Programmers can calculate the worst(maximum time to execute a program), average(average time to execute a program), and the best (minimum time to execute a program) case scenario of a program exploiting its asymptotic analysis.
Function analysis is an input-bounded mechanism, i.e., all parameters except input are supposed constant (the programs without input execute in a constant time). Complexity analysis refers to a class of functions for a program's behavior examination based on the size of inputs (especially large inputs). In this analysis:
  • Big O is an upper bound for the worst-case scenarios.
  • Big Ω is a lower bound for the best-case scenarios.
  • Big Θ is an upper and lower bound for the scenarios withBigΩ== BigO.

Return Type Resolver in C++

Return type resolver or return type overloading is one of the advanced concepts in C++ programming language, which exploits templated conversion operator and a proxy class to derive object types when the objects are initialized or allocated.

Return type resolver is employed to offer a generic object-independent assignment interface to deal with the function overloading challenges only using returned type. The general scheme of return type resolver in C++ is illustrated in Algorithm 1.

Multi-dimensional Array in C++

Programmers can define the multi-dimensional arrays(array of arrays) in C++ programming language, which arrange the elements in several dimensions. The elements of multi-dimensional arrays in C++ are located in tables with row order. The standard form of an M-dimensional array declaration is:
  • Elements_Type M_Dimensional_Array_Name [Dim1][Dim2][Dim3] … [DimM]

In this statement,

  • Elements_Type refers to the type of stored elements in the M-dimensional array that can be any valid data-type in C++. It should be noted that all data stored in a multi-dimensional array must be of the same type.
  • M_Dimensional_Array_Name displays the name of the M-dimensional array that can be any valid identifier in C++.
  • Dim1, Dim2, Dim3, …, DimMrepresents the size of M dimensions. Thus, the total number of elements stored in an M-dimensional array is computed by multiplying the length of dimensions (Dim1 × Dim2 × Dim3 × …× DimM).

Generalized Lambda Expressions in C++

One of the powerful capabilities added in C++11 is lambda expressions. They are generally pieces of code that are inserted into function call expressions or functions. Thus, programmers can exploit the combination of lambda expressions and auto keywords in C++ applications to decrease codes, enhance the efficiency of applications, and support parallel/sequential execution using behaviors as the arguments.

In C++ programming language, Lambda is a context-based phrase that usually points to one of three terms, including a closure object, a lambda expression, or a closure class.

The standardsyntax of a lambda expression is:

  • auto Lambda_expression = [](auto A, auto B) {return A + B;}

In this statement, Lambda_expression is the closure object, and [](auto A, auto B) { return A + B; } refers to the lambda expression. Although the closure class is invisible in the syntax above, it locates in the closure object’s type.

Resource Acquisition Is Initialization (RAII) in C++

Resource Acquisition Is Initialization (RAII), Destructor Releases (CADRe), Constructor Acquires (CA), or Scope-based Resource Management (SBRM) is a computer engineering phrase for statically-typed and object-oriented programming languages to define specific behaviors successfully. It related the resource to object lifetime fixedly, mostly automatic variables. In more detail, the constructor performs acquisition (resource allocation)during the initialization phase (object building), and the destructor releases allocated resources during the finalization (object destruction).

Resource acquisition had been expanded for several programming languages to manage resources and prevent exceptions.C++ is the most common language that supports RAIIto maintain resources between initialization and finalization steps. Thus, IfC++ programmers use RAII, they can claim“no resource leaks in the case of no object leaks.”

C++ programming language exploits some library classes to guarantee RAII in the applications, including:

  • std::string, std::vector, std::threadto acquire and release resources.
  • std::unique_ptr and std::shared_ptrto administer dynamic memories.
  • std::lock_guard, std::unique_lock, std::shared_lockto manipulatemutexes.
