C program to find middle among three number using function

In this tutorial, we will discuss the concept of C program to find middle among three numbers using function

This post describes how to find the middle number among three numbers using if statements in C language

There are many ways to find the middle number of the three numbers. but here, we mainly focus on using  if-else-if statements in C.

 

Using Nested if statements  to find the middle

#include <stdio.h>
#include <stdlib.h>
int middleNumber(int,int,int);//function prototype
int main()
{
    int num1,num2,num3;
    printf("Enter the three numbers\n");
    scanf("%d %d %d",&num1,&num2,&num3);//takes input from user
    printf("Middle number is %d",middleNumber(num1,num2,num3));//function call
    getch();
    return 0;
}

int middleNumber(int num1,int num2,int num3){//function definition
    int middle=0;

    if(num1>num2){
        if(num2>num3){
        middle=num2;
    }
    else if(num3>num1){
        middle=num1;
    }
    else{
        middle=num3;
    }
    }

    else{

        if(num2<num3){
        middle=num2;
    }
    else if(num3<num1){
        middle=num1;
    }
    else{
        middle=num3;
    }

}

}

When the above code is executed, it produces the following results

Enter the three numbers
23
45
78
Middle number is 45
