Generating integer sequences in x86 assembly assignment help

The assignment deals with the generation of a given integer sequence using assembly code. A sample program in C++ that implements the required functionality is given and must be converted to assembly. The implementation is based on the Irvine library. The following solution provided by our assembly assignment helpers demonstrates how to generate integers in x86.
