C Program to Generate Multiplication Table

In this example, you will learn to generate the multiplication table of a number entered by the user.
Multplication table

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

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


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).

Multiplication Table Up to a range

#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
