# C program to find Largest Number among three numbers

This program will take three integer numbers from user and find largest number among them; we will find largest number using two methods - if else and conditional operators.

## Largest Number among three numbers using nested if else

/* c program to find largest number among 3 numbers*/
#include <stdio.h>

int main()
{
int a,b,c;
int largest;

printf("Enter three numbers (separated by space):");
scanf("%d%d%d",&a,&b,&c);

if(a>b && a>c)
largest=a;
else if(b>a && b>c)
largest=b;
else
largest=c;

printf("Largest number is = %d",largest);

return 0;
}

## Largest Number among three numbers using ternary operator

Instead of using if else we can also get the largest number among three number by using Ternary Operator (? :) Operator in C.

### Code snippet

Consider the code snippet
largest = ((a>b && a>c)? a : ((b>a && b>c)? b : c));

## C program to find Largest Number among three numbers using ternary operator

/*using ternary operator (? :) */
#include <stdio.h>

int main()
{
int a,b,c;
int largest;

printf("Enter three numbers (separated by space):");
scanf("%d%d%d",&a,&b,&c);

largest =((a>b && a>c)?a:((b>a && b>c)?b:c));

printf("Largest number is = %d",largest);

printf("Largest number is = %d",largest);
return 0;
}

### Output

First Run:
Enter three numbers (separated by space): 10 20 30
Largest number is = 30

Second Run:
Enter three numbers (separated by space):10 30 20
Largest number is = 30

Third Run:
Enter three numbers (separated by space):30 10 20
Largest number is = 30

Fourth Run:
Enter three numbers (separated by space):30 30 30
Largest number is = 30
