C Program to find the largest among three numbers

Algorithm

Input: Input three numbers
output: Finds and displays the largest among the three input numbers

1. Start
2. Input three numbers say a, b, c
3. if a>b and b>c
   3.1 Print 'a' is greater
4. else if
   4.1 b>a and b>c
   4.2 Print 'b' is greater
5. else
   5.1 Print 'c' is greater
6. Stop

C Program

#include <stdio.h>

int main( )

{

   int a, b, c;

   printf("Enter first number: ");

   scanf("%d", &a);

   printf("Enter second number: ");

   scanf("%d", &b);

   printf("Enter third number: ");

   scanf("%d", &c);

   if (a > b && a > c) {

        printf("%d is the largest among %d, %d and %d", a, a, b, c);

    }

   else if (b > c && b > a) {

        printf("%d is the largest among %d, %d and %d", b, a, b, c);

    }

    else {

       printf("%d is the largest among %d, %d and %d", c, a, b, c);

   }

    return 0;
