C Exercises: Compute multiplication table of a given integer

C For Loop: Exercise-6 with Solution

Write a program in C to display the multiplication table of a given integer.

Pictorial Presentation:

Compute multiplication table of a given integer

Sample Solution:

C Code:

#include <stdio.h>
void main()
{
   int j,n;
   printf("Input the number (Table to be calculated) : ");
   scanf("%d",&n);
   printf("\n");
   for(j=1;j<=10;j++)
   {
     printf("%d X %d = %d \n",n,j,n*j);
   }
} 

Sample Output:

Input the number (Table to be calculated) : 15                                                                
                                                                                                              
15 X 1 = 15                                                                                                   
15 X 2 = 30                                                                                                   
15 X 3 = 45                                                                                                   
15 X 4 = 60                                                                                                   
15 X 5 = 75                                                                                                   
15 X 6 = 90                                                                                                   
15 X 7 = 105                                                                                                  
15 X 8 = 120                                                                                                  
15 X 9 = 135                                                                                                  
15 X 10 = 150

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
