Need to break out of the IF statement

[bitcyknw]

I need the code to go back to the beginning of the program after the User inputs Y in the IF statement. Every thing else in the code works fine I just cannot for the life of me figure out how to make it loop back to the beginning. Please help I am so confused. I have been working on for weeks. I am new to this forum so forgive me if I am not clear enough. The instructions for the game are below.

/*-----------------------------------------------------------------------------------
1. The program asks for input until a valid choice (4-20) is given by the user
2. The program asks if the user wants to play again after each round (y/n)
3. if yes (y), the user is asked to choose a number of sides again
4. if no (n), the program gives a thank you message and instructs the user to press [RETURN] to exit (and waits for [RETURN] before exiting)
--------------------------------------------------------------------------------------*/

#include<iostream>
#include<cstdlib>
#include<ctime>
using namespace std;


void chooseNumbers(int num, int roll, char answer);
void playagain(char answer, int num, int roll);


int main() {
int num; //integer for number
int roll; //integer for roll
srand(time(0)); //seed random number generator
char answer;

cout << "You are about to roll a single die" << endl;
cout << "How many sided die would you like to roll(4-20)? ";
cin >> num;
cin.ignore();

roll = 1 + rand() % num; //mods random number

//If you get wrong answer
chooseNumbers(num, roll, answer);

//Play again
playagain(answer, num, roll);


return 0;
}


void chooseNumbers(int num, int roll, char answer) {

while (num < 4 || num > 20){
cout << "Please play again and enter a number between 4 and 20" << endl;
cin >> num;
}

cout << "You rolled: " << endl;
cout << roll << endl;

}

void playagain(char answer, int num, int roll)
{
while (answer != 'Y' && answer != 'N') {

cout << "Do you want to play again? Type in Y for yes, or N for no: " << endl;
cin >> answer;
}

if (answer == 'Y') {

}

else if (answer == 'N') {

cout << "Thank you! Please press RETURN to exit." << endl;
cin.ignore();
cin.get();
cout << "Exiting..." << endl;
}
}

I wish someone would help me. I've asked everywhere :(

Make sure you pay attention to this when you post.

Most forums have similar requirements when it comes to posting code.

So you present code like this, not an unformatted mess.

#include<iostream>
#include<cstdlib>
#include<ctime>
using namespace std;


void chooseNumbers(int num, int roll, char answer);
void playagain(char answer, int num, int roll);


int main()
{
  int num;                      //integer for number
  int roll;                     //integer for roll
  srand(time(0));               //seed random number generator
  char answer;

  cout << "You are about to roll a single die" << endl;
  cout << "How many sided die would you like to roll(4-20)? ";
  cin >> num;
  cin.ignore();

  roll = 1 + rand() % num;      //mods random number

  //If you get wrong answer
  chooseNumbers(num, roll, answer);

  //Play again
  playagain(answer, num, roll);


  return 0;
}


void chooseNumbers(int num, int roll, char answer)
{

  while (num < 4 || num > 20) {
    cout << "Please play again and enter a number between 4 and 20" << endl;
    cin >> num;
  }

  cout << "You rolled: " << endl;
  cout << roll << endl;

}

void playagain(char answer, int num, int roll)
{
  while (answer != 'Y' && answer != 'N') {

    cout << "Do you want to play again? Type in Y for yes, or N for no: " << endl;
    cin >> answer;
  }

  if (answer == 'Y') {

  }

  else if (answer == 'N') {

    cout << "Thank you! Please press RETURN to exit." << endl;
    cin.ignore();
    cin.get();
    cout << "Exiting..." << endl;
  }
}

An answer to your question would be to make playagain return a result.

// your parameters were useless
bool playagain(void)
{
  char answer;
  while (answer != 'Y' && answer != 'N') {

    cout << "Do you want to play again? Type in Y for yes, or N for no: " << endl;
    cin >> answer;
  }

  if (answer == 'Y') {
    return true;
  }

  else if (answer == 'N') {

    cout << "Thank you! Please press RETURN to exit." << endl;
    cin.ignore();
    cin.get();
    cout << "Exiting..." << endl;
    return false;
  }
}

Then in main, you can do

do {
  // the game
} while( playagain() );

OK thank you so much. Sorry I am just learning how to program and I do not know what I am doing clearly lol. I have not learned how to use bool functions yet but I will try it out. Thank you.
