Multiplication table program in c

This program will compute the multiplication table of a given integer value from the user for the given specific number of rows. For example, if the user entered an input value 5 and the number of rows is 10 then it will form a multiplication table of 5 with 10 rows.

#include <stdio.h>
int main()
{
    int r,n,i;
    printf("Enter no of rows:");
    scanf("%d",&r);
    if(r>0)
    {
        printf("Enter a value:");
        scanf("%d",&n);
        i=1;
        while(i<=r)
        {
            printf("\n%d*%d=%d",n,i,n*i);
            i=i+1;
        }
    }
    else
        printf("\ninvalid row value");
    return 0;
}

Output:

Enter no of rows:10                                                                                                                                          

Enter a value:5                                                                                                                                              

                                                                                                                                                             

5*1=5                                                                                                                                                        

5*2=10                                                                                                                                                       

5*3=15

……….

………     

5*8=40                                                                                                                                                       

5*9=45                                                                                                                                                       

5*10=50 

Multiplication table program in c language

This program will compute the multiplication tables of given two integer value from the user for the 10 rows. For example, if the user entered input values 2 and 4  then it will form multiplication tables from 2 to 4 for 10 rows.

#include <stdio.h>
int main()
{
  int n1,n2,n,i;
  printf("Enter two values: ");
  scanf("%d%d",&n1,&n2);
  i=1;
  while(i<=10)
  {
    printf("\n");
    n=n1;
    while(n<=n2)
    {
      printf("%3d*%2d=%2d",n,i,n*i);
      n=n+1;
    }
    i=i+1;
  }
  
  return 0;
}

Output:

Enter two values: 2 4                                                                                                                                                                                                                                                               

  2* 1= 2  3* 1= 3  4* 1= 4                                                                                                                                  

  2* 2= 4  3* 2= 6  4* 2= 8                                                                                                                                  

  2* 3= 6  3* 3= 9  4* 3=12  

  ……….   ……….. ……….

2* 9=18  3* 9=27  4* 9=36                                                                                                                                  

2*10=20  3*10=30  4*10=40
