C Program to Generate Multiplication Table

Example to generate the multiplication table of a number (entered by the user) using for loop.
Multplication table

To understand this example, you should have the knowledge of following C programming topics:

The program takes an integer input from the user and generates the multiplication table up to 10.

Example #1: Multiplication Table Up to 10

#include <stdio.h>
int main()
{
    int n, i;

    printf("Enter an integer: ");
    scanf("%d",&n);

    for(i=1; i<=10; ++i)
    {
        printf("%d * %d = %d \n", n, i, n*i);
    }
    
    return 0;
}

Output

Enter an integer: 9
9 * 1 = 9
9 * 2 = 18
9 * 3 = 27
9 * 4 = 36
9 * 5 = 45
9 * 6 = 54
9 * 7 = 63
9 * 8 = 72
9 * 9 = 81
9 * 10 = 90

Here's a little modification of the above program to generate the multiplication table up to a range (where range is also a positive integer entered by the user).

Example #2: Multiplication Table Up to a range (entered by the user)

#include <stdio.h>
int main()
{
    int n, i, range;

    printf("Enter an integer: ");
    scanf("%d",&n);

    printf("Enter the range: ");
    scanf("%d", &range);

    for(i=1; i <= range; ++i)
    {
        printf("%d * %d = %d \n", n, i, n*i);
    }

    return 0;
}

Output

Enter an integer: 12
Enter the range: 8
12 * 1 = 12 
12 * 2 = 24 
12 * 3 = 36 
12 * 4 = 48 
12 * 5 = 60 
12 * 6 = 72 
12 * 7 = 84 
12 * 8 = 96
