So this is for school, and it's supposed to get 3 numbers from the input and output if no numbers are the same, 2 numbers are the same, or all the numbers are the same. I know I'm supposed to use an else if statement but not sure really how to do it. Here's what I have so far

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

int num1, num2, num3;

// Get User Input

cout << "Please enter the first number (an integer): ";

cin >> num1;

cout << "Please enter the second number (an integer): ";

cin >> num2;

cout << "Please enter the third number (an integer): ";

cin >> num3;

cout << endl;

// Go Program Go!

if (num1 == num2)

cout << "Exactly two of the numbers are the same." << endl;

if (num2 == num3)

cout << "Exactly two of the numbers are the same." << endl;

if (num1 == num3)

cout << "Exactly two of the numbers are the same." << endl;

else

cout << "None of the numbers are the same." << endl;

cout << endl;

return 0;

}

It's displaying both couts, what's causing the else to output?

return 0;
