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.
/* 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;
}
Using Ternary Operator (? : Operator)
Instead of using if else we can also get the largest number among three number by using Ternary Operator (? :) Operator in C.
Consider the code snippet
largest = ((a>b && a>c)? a : ((b>a && b>c)? b : c));
Consider the example,
/*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
