functions

[even821]

i was bored today in class so i decided to do some coding. i was trying to learn more about how functions worked. i created a simple "number guessing" program were there are 3 functions. one for getting the useres number guess, one for the main program (telling the user if he guessed right or not) and finally int main().

the problem i have is that my repeating prosess does not work like its suppose to. anyways this is my code:

#include "stdafx.h"
#include <iostream>
#include <string>

using namespace std;

bool mainGame(int number){
	bool tryAgain = false;
	string answer = "";

	if (number < 821){
		cout << "that number is too low\n";
		cout << "wanna try again? ";
		cin  >> answer;

		if (answer == "yes"){
			tryAgain = true;
		}
		else if (answer == "no"){
			tryAgain = false;
		}
		else{
			cout << "that is an invalid answer.";
		}
	}
	else if (number > 821){
		cout << "that number is too high\n";
		cout << "wanna try again? ";
		cin  >> answer;

		if (answer == "yes"){
			tryAgain = true;
		}
		else if (answer == "no"){
			tryAgain = false;
		}
		else{
			cout << "that is an invalid answer.";
		}
	}
	else if (number == 821){
		cout << "that is correct";
	}

	return tryAgain;
}
int getNumber(){
	cout << "guess my number: ";
	int number = 0;
	cin >> number;
	
	return number;
}
int main(){
	bool tryAgain = true;

	while (tryAgain == true){
		int number = getNumber();
		bool tryAgain = mainGame(number);
	}

	system("Pause>nul");
	return 0;
}

can anyone tell me what i did wrong?

please keep in mind that im still just a beginner at coding so i might not have gotten anything right...

on line 59, you are creating a new variable named tryAgain
don't do that. Just assign the return value.
