2. The C code to calculate the product of two integers is as follows:
// C code
// This program will product two integer numbers to yield a third integer number.
// Developer: Faculty CMIS102

C PROGRAMMING3
// Date: Jan 31, XXXX
#include <stdio.h>
int main ()
{
int x, y, z; /* variable definition: */
x = 0; y = 0; /* variable initialization */
printf("Developer: Faculty CMIS102 ");
printf("Date: Jan 31, 2020");
printf("\n enter a value for x: \t"); //Prompt for user input
scanf("%d" , &x); //Get the user response
printf("\n enter a value for y: \t"); //Prompt for user input
scanf("%d", &y); //Get the user response
z = x * y; //Calculate the product
//Print out the answer
//Note: x,y,z are Declared as Integer, hence we use %d as the formatter.
//Wherever you put the formatter symbol (i.e %d) is where the variable value is substituted.
//The order of the substitution is the same as the order of the variable list at the end (a,b,c)
//Note the tab (\t) in the statement also.
printf("\n\n The product of Integers (%d) and (%d) is : \t %d \n", x, y, z);
// value of x is substituted here ^ value of y ^ value z ^ here
