C Program for Multiplication table

C Program for Multiplication table | In mathematics, a multiplication table is a mathematical table used to define a multiplication operation for an algebraic system.

Here we will develop different C program for Multiplication table using for loop, using while loop, using do-while loop, from 1 to 10 and from 1 to N.

Multiplication table program in C using for loop

In this program, we will use two variables num, and i. The variable num is used to store the input integer number and the variable ‘i’ is used to iterate the loop. Product of the number is given by num*i;

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

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

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

     return 0;
}

Output:-

C Program to print Multiplication table using while loop

Below is the C program for the multiplication table using a while loop. The while loop is pre-test loop, where firstly the condition is checked and if the condition is true then only the statements of the while loop execute.

 #include<stdio.h>
 int main()
 {
      int num, i=1;

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

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

      return 0;
 }

Output:-

Multiplication Table using do-while loop

We can also print table using do while loop in C. The do-while loop is post-test loop. In the do-while loop, the statements of the do-while loop are executed after that, the condition is evaluated, and if the condition is true then again the statements of the do-while loop are executed.

 #include<stdio.h>
 int main()
 {
      int num, i=1;

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

      do
      {
        printf(" %d * %d = %d\n", num, i, num*i);
        i++;
      } while (i<=10);

      return 0;
 }

C program to print multiplication table from 1 to 10

Sometimes, we need to write a program to print the multiplication table from 1 to 10. In this case, nested loops can help us to solve the problem. Outer loop used to display column and inner loop used to display the row of the multiplication table.

 #include<stdio.h>
 int main()
 {
    printf("The multiplication table from 1 to 10 is: \n");

    for(int i=1; i<=10; i++)
    {
      for(int j=1; j<=10; j++)
      printf("%d*%d=%d\t", j, i, j*i);

      printf("\n"); //Next line
    }
    return 0;
 }

Output:-

The multiplication table from 1 to 10 is: 
1*1=1	2*1=2	3*1=3	4*1=4	5*1=5	6*1=6	7*1=7	8*1=8	9*1=9	10*1=10	
1*2=2	2*2=4	3*2=6	4*2=8	5*2=10	6*2=12	7*2=14	8*2=16	9*2=18	10*2=20	
1*3=3	2*3=6	3*3=9	4*3=12	5*3=15	6*3=18	7*3=21	8*3=24	9*3=27	10*3=30	
1*4=4	2*4=8	3*4=12	4*4=16	5*4=20	6*4=24	7*4=28	8*4=32	9*4=36	10*4=40	
1*5=5	2*5=10	3*5=15	4*5=20	5*5=25	6*5=30	7*5=35	8*5=40	9*5=45	10*5=50	
1*6=6	2*6=12	3*6=18	4*6=24	5*6=30	6*6=36	7*6=42	8*6=48	9*6=54	10*6=60	
1*7=7	2*7=14	3*7=21	4*7=28	5*7=35	6*7=42	7*7=49	8*7=56	9*7=63	10*7=70	
1*8=8	2*8=16	3*8=24	4*8=32	5*8=40	6*8=48	7*8=56	8*8=64	9*8=72	10*8=80	
1*9=9	2*9=18	3*9=27	4*9=36	5*9=45	6*9=54	7*9=63	8*9=72	9*9=81	10*9=90	
1*10=10	2*10=20	3*10=30	4*10=40	5*10=50	6*10=60	7*10=70	8*10=80	9*10=90	10*10=100

Print Multiplication Table from 1 to N

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

   printf("Enter number of tables: ");
   scanf("%d",&n);

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

   return 0;
}

In this program, we used two for loop. Outer for loop used to display column and inner for loop used to display the row of the multiplication table.

In our computer screen, there is a limitation on displaying characters. After a certain number of character, this program gives output but not displayed in the same manner. Try it for n=15, and observe it.
