# C++ Program to Implement Sets Assignment Solution.

## Instructions

Objective
Writing a program to implement sets in C++ can be a valuable learning experience. Sets are containers that store unique elements in no particular order, making them useful for various applications. By utilizing the standard template library (STL) in C++, you can easily create and manipulate sets. If you need help with your C++ assignment focused on set implementation or any related concepts, feel free to ask for guidance and clarification.

## Requirements and Specifications Source Code

```#include #include #include #include #include #include "Set.h" #include #ifndef MAX_FILE_LENGTH #define MAX_FILE_LENGTH 255 #endif // MAX_FILE_LENGTH using namespace std; /**  * Read the input set from the input stream, and output the subsets  * to the output stream.  */ void get_subsets(istream& i1, ostream& o) {  Set set1;  set1.scan(i1); // read the set from the input file  set1.print(o, "A="); // print the set to the output file     /* Please put your code here. */     o << "Subsets of A:" << std::endl;     // Loop from 0 to 2^n-1 where n is the size of the set     int n = set1.getsize();     int n_subsets = pow(2, n);     for(int i = 0; i < n_subsets; i++) {         o << "{";         for(int j = 0; j < n; j++) {             if(i & (1 << j)) { // binary operator                 o << set1.getelements()[j];                 if(j < n-1) {                     o << ",";                 }             }         }         o << "}";         if(i < n_subsets-1) {             o << ",";         }         else {             o << ".";         }         o << std::endl;     }     // Finally, write the number of subsets     o << "There are " << pow(2, set1.getsize()) << " subsets of A.";     // TODO: get all the subsets of the input set and print the result } /*  * This program accepts three command line arguments:  * argv is for the path to input file  * argv is for the path to the output file  */ int main(int argc, char* argv[]) {     char file1[MAX_FILE_LENGTH], file2[MAX_FILE_LENGTH];  // file1 is for the input, file2 is for the output     strcpy(file1, argv);     strcpy(file2, argv);     ifstream i1 (file1);     ofstream o (file2);     if (i1.is_open() && o.is_open()) {         get_subsets(i1, o);         i1.close();         o.close();     }     else {         cout << "Unable to open the file(s)." << endl;     } }```
