Thread: Adding Random Numbers help

I need to create a program where the user selects addition, subtraction, or multiplication, and when they select one, 2 random numbers appear, and they must put in the right answer. The problem is, i cant get the correct answer. It just says: Would you like to play again?

Code:

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

void displayHeader();
void problemType();
void calcRealAnswer();
bool goAgain();

int calculateRandomNumber();

int choice = 0;
int userAnswer = 0;
int realAnswer = 0;
float randomNumber = 0;


int main(){
    srand((unsigned)time(0)); 

do {
        displayHeader();
        problemType();
        }while(goAgain());
        system("cls");

cin.get();
cin.get();
return 0;
}

void displayHeader()
{
     cout<<"Welcome to my math game program. Sit back and enjoy!!"<<endl;
     cout<<endl;
}

void problemType()
{

     cout << "Enter the number for the problem type desired:" << endl;
     cout << "1.  Addition"  << endl;
     cout << "2.  Subtraction"  << endl;
     cout << "3.  Multiplication"  << endl;
     cout << "Enter choice: ";
     cin >> choice;
     
     if (choice==1){
     cout << calculateRandomNumber();
     cout << " + "; 
     cout << calculateRandomNumber();
     cout << " = ";
     cin >> userAnswer;}
     
     else if (choice==2){
     cout << calculateRandomNumber();
     cout << " - ";
     cout << calculateRandomNumber();
     cout << " = ";
     cin >> userAnswer;}
     
     else if (choice==3){
     cout << calculateRandomNumber();
     cout << " * "; 
     cout << calculateRandomNumber();
     cout << " = ";
     cin >> userAnswer;}
     
     else{
     cout << "Invalid answer. Please select a valid choice: ";
     cin >> choice;
     }
     
}

bool goAgain()
{
     char answer;

     cout << "Would you like to play again? ";
     cin >> answer;

     system("cls");
  while(answer != 'Y' && answer != 'N')
  {
  cout << "Invalid choice.  Would you like to go again? ";
  cin >> answer;
  }

  cout << endl;
  

  if(answer == 'Y')
  return true;
  else
  return false;
    }

int calculateRandomNumber(){
    
    return (rand()%100) + 1;
}
