Write a C program to define a macro that can calculate the greater of two of its arguments. Use this macro to calculate the greatest of 4 integers.

#include <stdio.h>

#define MAX(x,y) ((x>y)?x:y)

int main()
{
	int a,b,max;
	
	printf("Enter first number: ");
	scanf("%d",&a);
	printf("Enter second number: ");
	scanf("%d",&b);	
	
	max=MAX(a,b);
	printf("Maximum number is: %d\n",max);
	
	return 0;
}

Output

Enter first number: 100 
Enter second number: 200
Maximum number is: 200
