define max size in c code example

Example 1: How to define Max in define in c

// For defining x > y
#define MAX(X, Y) (((X) > (Y)) ? (X) : (Y))
// For defining x < y
#define MIN(X, Y) (((X) < (Y)) ? (X) : (Y))

Example 2: max number in c

#include <stdio.h>
#include <stdlib.h>

int main()
{
    double num1,num2,maxNum,minNum;

    printf("Enter a number: ");
    scanf("%lf", &num1);
    printf("Enter another number: ");
    scanf("%lf", &num2);
    printf("\n");

    if (num1 > num2){
        maxNum = num1;
        minNum = num2;
      
        printf("The largest number is %f \n",maxNum);
        printf("The smallest number is %f \n",minNum);
    }else if (num1 < num2){
        maxNum = num2;
        minNum = num1;
      
        printf("The largest number is %f \n",maxNum);
        printf("The smallest number is %f \n",minNum);
    }printf("The numbers are equal");

    return 0;
