Write a Program in C++ That Square Function Used to Demonstrate The Function Call Stack and Activation Records

// square function used to demonstrate the function 

// call stack and activation records.

#include <iostream>

using namespace std;

int square( int ); // prototype for function square

int main()

{

   int a = 10; // value to square (local automatic variable in main)

   cout << a << " squared: " << square( a ) << endl; // display a squared

} // end main

// returns the square of an integer

int square( int x ) // x is a local variable

{

   return x * x; // calculate square and return result

} // end function square
