C Program to Generate Multiplication Table

Howdy readers, today you will learn how to write a C program to generate a multiplication table.

This tutorial takes an integer from the user, store the integer in a variable and then use a for loop to generate the multiplication table of the entered integer.

In this tutorial, we will be writing two programs. In the first program, the program will display the multiplication table up to 10.

While in the second program, the program asks the user to enter a range, then it will display the multiplication table till the range specified by the user.

So, without any delay, let’s begin this tutorial.

C Program to Generate Multiplication Table

C Program

// C Program to Generate Multiplication Table
#include <stdio.h>

int main(){
    int num;
    
    // Taking Input
    printf("Enter a positive integer: ");
    scanf("%d", &num);
    
    // Multiplication Table
    printf("Multiplication table of %d is: \n", num);
    for (int i = 1; i <= 10; i++){
        printf("%d * %d = %d \n", num, i, num*i);
    }
    
    return 0;
}

Output

Enter a positive integer: 7
Multiplication table of 7 is: 
7 * 1 = 7 
7 * 2 = 14 
7 * 3 = 21 
7 * 4 = 28 
7 * 5 = 35 
7 * 6 = 42 
7 * 7 = 49 
7 * 8 = 56 
7 * 9 = 63 
7 * 10 = 70 
C Program to Generate Multiplication Table

Explanation

    int num;

We have declared an int data type variable num

    printf("Enter a positive integer: ");
    scanf("%d", &num);

The program takes an integer value from the user using the scanf() function. The integer is stored in the num variable.

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

Then, we used a for loop to print a multiplication table of num up to 10

The for loop iterates the loop from i = 1 to i = 10. In each iteration of the loop, num * i is printed on the screen. After that, the iteration is incremented by 1

This loop keeps on executing until i <= 10 condition becomes False.

C Program to Generate Multiplication Table Up to a Range

C Program

// C Program to Generate Multiplication Table Up to a Range
#include <stdio.h>

int main(){
    int num, range;
    
    // Taking Input
    printf("Enter a number: ");
    scanf("%d", &num);
    
    do {
        printf("Enter the maximum value of the range (Positive integer): ");
        scanf("%d", &range);
    }while (range <= 0);
    
    // Multiplication Table
    printf("Multiplication table of %d till range %d is: \n", num, range);
    for (int i = 1; i <= range; i++){
        printf("%d * %d = %d \n", num, i, num*i);
    }
    
    return 0;
}

Output

Enter a number: 2
Enter the maximum value of the range (Positive integer): 15
Multiplication table of 2 till range 15 is: 
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 
2 * 11 = 22 
2 * 12 = 24 
2 * 13 = 26 
2 * 14 = 28 
2 * 15 = 30 
C Program to Generate Multiplication Table Up to a Range

Explanation

    int num, range;

In this program, we have declared two int data type variables num and range.

    printf("Enter a number: ");
    scanf("%d", &num);

The input is taken from the user. The input value is stored in the num variable.

    do {
        printf("Enter the maximum value of the range (Positive integer): ");
        scanf("%d", &range);
    }while (range <= 0);

Then, we used a do-while loop to check whether the range entered by the user is positive or not. If the range is not positive, then the user is asked to enter the value of the range again.

This loop will keep on executing until the user enters a positive range. 

Once a positive range is entered, this program will print the multiplication table of num.

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

The for loop iterates the loop from i = 1 to i = range. Within the loop, n*i is printed and iteration is incremented by 1.

This loop keeps on executing till i <= range condition is True. If the i <= range condition becomes False, then the loop terminates, and the multiplication table is printed on the screen.

Conclusion

Today you learned how to write a C program to generate a multiplication table.

Besides that, you have also learned how to generate a multiplication table up to a certain range.

Now, you can calculate and print the multiplication table of any integer using the above logic.
