C Program to Find the Largest Number Among Three Numbers

In this example, We take three integer values as input and check which number is largest or greatest among them.

C Program to find largest number among three numbers:

For finding greatest or largest number we are going to use if...else in and nested if...else.

Example :

	
#include  <stdio.h>
void main()
{
    int num1, num2, num3;
    
    printf("Enter three integer number :: ");
    scanf("%d %d %d", &num1, &num2, &num3);
    printf("num1 = %d\tnum2 = %d\tnum3 = %d\n", num1, num2, num3);
    if (num1 > num2)
    {
        if (num1 > num3)
        {
            printf("num1 is the greatest among three \n");
        }
        else
        {
            printf("num3 is the greatest among three \n");
        }
    }
    else if (num2 > num3)
        printf("num2 is the greatest among three \n");
    else
        printf("num3 is the greatest among three \n");
}
	

Output :

	
		//Output :- 1
		Enter three integer number :: 100 200 300
		num1 = 100      num2 = 200      num3 = 300
		num3 is the greatest among three
		//Output 2
		Enter three integer number :: 200 250 200
		num1 = 200      num2 = 250      num3 = 200
		num2 is the greatest among three
