int main()
{
int fno, sno, *ptr, *qtr, sum;

printf("\n\n Pointer : Add two numbers :\n");
printf("--------------------------------\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;

## 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.
