C Exercises: Pictorial: Add two numbers.

Sample Solution:

C Code:

#include <stdio.h>
int main()
   int fno, sno, *ptr, *qtr, sum;
   printf("\n\n Pointer : Add two numbers :\n"); 
   printf(" Input the first number : ");
   scanf("%d", &fno);
   printf(" Input the second  number : ");
   scanf("%d", &sno);   
   ptr = &fno;
   qtr = &sno;
   sum = *ptr + *qtr;
   printf(" The sum of the entered numbers is : %d\n\n",sum);
   return 0;

Sample Output:

 Pointer : Add two numbers :                                                                                  
 Input the first number : 5                                                                                   
 Input the second  number : 6                                                                                 
 The sum of the entered numbers is : 11

C Programming: Tips of the Day

How to format strings using printf() to get equal length in the output?

You can specify a width on string fields, e.g.

printf("%-20s", "initialization..."); 

And then whatever's printed with that field will be blank-padded to the width you indicate.

The - left-justifies your text in that field.
