In this example, the user is asked to enter two integers. Then, we we will subtract from one variable from another and displayed on the screen.
To understand this example, you should have the knowledge of the following C programming topics:
#include"stdio.h"
void main()
{
// variable declaration
int num1, num2, subResult;
printf("Enter two no: ");
scanf("%d%d",&num1,&num2);
subResult = num1 - num2;
// Print result
printf("subtraction result =%d \n", subResult);
}Enter two no: 6 3
sum=3

Algorithm:
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
