C++ Program to Convert Decimal Number to Binary using Stacks

This C++ program, using a stack, displays the bits of a binary number when the corresponding decimal number is entered as input.

Here is the source code of the C++ program to display a linked list in reverse. The C program is successfully compiled and run on DevCpp, a C++ compiler. The program output is also shown below.
