C Program to Define a Macro for Finding the Biggest of Two Numbers

Writing a C program to define a macro for finding the biggest of two numbers means creating a piece of code that can be used to compare two numbers and determine which one is the largest. This macro can then be used in other parts of the program to make decisions based on the comparison result.

To define a macro for finding the biggest of two numbers in C, we can use the following code:

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

This macro takes two numbers as input and returns the bigger of the two numbers. The macro uses the ternary operator to compare the two numbers and return the bigger number.

Here is an example of how to use the MAX() macro:

int main() {
  int num1, num2, max;

  printf("Enter two numbers: ");
  scanf("%d %d", &num1, &num2);

  max = MAX(num1, num2);

  printf("The biggest of %d and %d is %d\n", num1, num2, max);

  return 0;
}

Output:

Enter two numbers: 10 20
The biggest of 10 and 20 is 20

We can also use the MAX() macro in expressions. For example, the following code will print the biggest of 10 and 20 to the console:

int main() {
  printf("The biggest of 10 and 20 is %d\n", MAX(10, 20));

  return 0;
}

Output:

The biggest of 10 and 20 is 20

Macros can be a useful way to make our code more concise and readable. However, it is important to use them carefully, as they can also make our code more difficult to debug

Example 03: define a macro for finding the biggest of two numbers

#include<stdio.h>
#define big(a,b) if(a>b)\
                        printf(#a " is greater :%d\n",a);\
                        else\
                        printf(#b " is greater....%d\n",b);
void main()
{
    int i=10,j=20;
    big(i,j);//micro call
}

Output:
j is greater....20
