C Exercises: Second largest among three integers

C Basic-II: Exercise-3 with Solution

Write a C program that accepts three integers from the user and find second largest number among these.

Constraints:

• 1≤ x ≤100
• 1≤ y ≤100
• 1≤ z ≤100

Sample Date:

(1 , 2, 3) -> 2
(10, 12, 24) -> 12
(34, 21, 30) -> 30

C Code:

#include<stdio.h>
int test(int x, int y, int z)
{
    if ((x>=y && x<=z)||(x<=y && x>=z)) 
	return 1;
    else 
	return 0;
}

int main()
{
    int x, y, z;
    printf("Input the first integer: ");
    scanf("%d", &x);
    printf("Input the second integer: ");
    scanf("%d", &y);
    printf("Input the third integer: ");
    scanf("%d", &z);
    printf("\nSecond largest number among said three integers: ");
    if (test(x,y,z))
	 printf("%d\n",x);
    else if (test(y,x,z)) 
	 printf("%d\n",y);
    else printf("%d\n",z);    
    return 0;
} 

Sample Output:

Input the first integer: Input the second integer: Input the third integer: 10, 12, 24
Second largest number among said three integers: 12
