C Program to find Largest of 3 numbers

Let’s see how to write a simple C program to Find the Largest number among three numbers. The logic is to get 3 numbers from the user and use the If condition to print out the Largest numbers among them.

#include <stdio.h>

int main()
{
    int numOne, numTwo, numThree, temp, largest;
    
    //get the number from the user 
    printf("Number 1:");
    scanf("%d", &numOne);
    
    printf("Number 2:");
    scanf("%d", &numTwo);
    
    printf("Number 3:");
    scanf("%d", &numThree);
    
    //use the ternary operator to 
    //find the largest number between numOne and numTwo and store it in temp variable 
    temp = (numOne > numTwo) ? numOne : numTwo;
    
    //Now compare the temp & numThree variable to find the largest number of 3 
    largest = (numThree > temp) ? numThree : temp;
    
    //print the Largest number
    printf("Largest of 3 number is : %d", largest);
    
    return 0;
}

Go through the above program and read the comments to understand it. Create a new file and copy-paste the above program to execute it.

This program is useful for school/college students or those who are learning the basics of the C programming language.

From this program, you can get the knowledge of the below items:

1. How to compare two Integers in C
2. How to use Ternary if Condition in C (Single line If condition in C Programming)
3. Store a value in temp variable in C

Hope this helps you!. All the best
