C Program to print the values using macro substitution.

/* C Program to illustrate preprocessor */

#include<stdio.h>

#include <conio.h>

#define VAL 40 /* macro substitution */

#undef VAL

#define VAL 40

void main()

{

printf ("The value is: %d\n", VAL);

} /* main */

OUTPUT

The value is: 40

EXPLANATION: This program displays the value using printf() statement which is defined in preprocessor.
