2.Write a C program to find addition of two numbers with multi-line comments to write down the purpose of every steps.

#include <stdio.h>
int main()
{
int a,b,total=0;
/* 1 Ask user to enter first number and store the number in a variable
2 Ask user to enter second number and save it in a variable
3 Add the two numbers and put the result in total
4 show or display the numbers and their total
*/
printf(“\n Enter a first number”);
scanf(“%d”,&a);
printf(“\n Enter a second number”);
scanf(“%d”,&b);
total=a+b;
printf(“\n Sum of %d + %d=%d”,a,b,total);
return 0;
}
