C++ program to find middle of 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 if-else-if statements to find the middle number.

Using Nested if statements to find the middle

Program

#include <iostream>
#include <conio.h>
using namespace std;

int middleNumber(int,int,int);
int main()
{
    int num1,num2,num3;
    cout<<"Enter the three numbers\n";
    cin>>num1>>num2>>num3;//takes input from user
    cout<<"Middle number is " <<middleNumber(num1,num2,num3);
    getch();
    return 0;
}

int middleNumber(int num1,int num2,int num3){
    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
45
56
78
Middle number is 45
