As we have discussed in the last post (how to use printf in function like macro?) that we can use printf() in Macros.

Here, we have to define a Macro that will accept an argument and print it by using printf() function.

Macro definition

    #define PRINT(val) (printf("value is: %d\n",val))

Example

#include <stdio.h>

#define PRINT(val) (printf("value is: %d\n",val))

//Main code
int main(){
	
	PRINT(10);
	PRINT(100);
	PRINT(-12);
	PRINT(0);
	
	return 0;	
}

Output

value is: 10
value is: 100
value is: -12
value is: 0
