# C Program to Find the Maximum of Two Numbers using Conditional Operator

In this article, we will learn to find the maximum of two numbers using a conditional operator in C programming.

The program takes two integer inputs from the user and prints the maximum of the two as a result.

Sample Input:

``````Enter first number: 20
Enter second number: 30``````

Output:

``30 is the Largest``

Before diving into the program, let’s first understand how the conditional operator works in C language.

The conditional operator which is also known as a ternary operator, takes three operands, the `condition`, `expression1` and `expression2`:

`condition ? expression1 : expression2;`

If the `condition` evaluates to true, the first expression i.e. `expression1` executes, otherwise, the second expression i.e. `expression2` executes.

We can also store the result of the conditional operator in a variable as follows:

`variableName = condition ? expression1 : expression2;`

The variable `variableName` will hold the value of the `expression1` if the condition evaluates to true, otherwise, it will hold the value of the `expression2`.

To find the maximum of the two numbers using the conditional operators, you can use the following approach:

• Declare two integer variables `num1` and `num2` to store the two numbers. Also declare a third variable `max` which will hold the maximum of the two numbers.
• Take the first number from the user using the scanf() function and store it in the `num1` variable.
• Take the second number from the user using the scanf() function and store it in the `num2` variable.
• Store the result of the conditional operator `num1 > num2?num1:num2;` in the `max` variable.
• The conditional operator returns `num1` if the num1 is greater than num2, otherwise, it returns `num2`.
• The maximum number is stored in the `max` variable. Print its value as a result.

The following program shows how you can use the conditional operator to find the maximum of the two numbers in C programming:

```// C program to find the maximum of the two numbers
// using the Conditional operator
#include <stdio.h>

int main(){

// Declare the variables
int num1, num2, max;

// Get the first number
printf("Enter first number: ");
scanf("%d", &num1);

// Get the second number
printf("Enter second number: ");
scanf("%d", &num2);

// Returns num1 if num1>num2, otherwise, returns num2
max = num1 > num2 ? num1 : num2;

// Print the largest number(stored in max variable)
printf("%d is the Largest", max);

return 0;
}```

Output:

```Enter first number: 20
Enter second number: 30
30 is the Largest```

Please note that the above program does not give the correct output if both numbers are equal to each other.

If you also want to put the equality check on the two numbers, use the `if...else` statements instead.
