Program Code

#include<stdio.h>
int main()
{
    int i=1;
    while(i<=10)
    {
        printf("2 * %d = %d\n",i,2*i);
        i++;
    }
    return 0;
}

Output

2 * 1 = 2
2 * 2 = 4
2 * 3 = 6
2 * 4 = 8
2 * 5 = 10
2 * 6 = 12
2 * 7 = 14
2 * 8 = 16
2 * 9 = 18
2 * 10 = 20

Explanation

This program prints a multiplication table of 2 from 1 to 10. We have used while loop to achieve our result. Initially i is assigned to 1. The condition to be tested is i<=10. After executing the loop each time, the value of i is increased by 1. When the value of i becomes 11, the condition becomes false and the loop is terminated.

How to learn from this program

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.

Practice suggestion

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.
