C program to print multiplication table by using for Loop

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.

Algorithm

Given below is an algorithm to print multiplication table by using for loop in C language −

Step 1: Enter a number to print table at runtime.
Step 2: Read that number from keyboard.
Step 3: Using for loop print number*I 10 times.
      // for(i=1; i<=10; i++)
Step 4: Print num*I 10 times where i=0 to 10.

Example

Following is the C program for printing a multiplication table for a given number −

#include <stdio.h>
int main(){
   int i, num;
   /* Input a number to print table */
   printf("Enter number to print table: ");
   scanf("%d", &num);
   for(i=1; i<=10; i++){
      printf("%d * %d = %d\n", num, i, (num*i));
   }
   return 0;
}

Output

When the above program is executed, it produces the following result −

Enter number to print table: 7
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
