How to link rand() to a while loop condition? - c++

Question

I'm making a simple coin flip game and i'm not sure how to get it to print out a result if that makes sense. basically I'm not sure what to make the while condition to see if the answer is true or false. here is what i have so far. any help would be appreciated
#include <iostream>
#include <ctime>
using namespace std;
int main()
{
srand(static_cast<unsigned int>(time(0)));
char answer;
int bank = 10;
int guess;
int h = 0;
int t = 1;
cout << "Welcome to the coin flip game. It cost a dollar to play." << endl;
cout << "If you guess correctly you will will $2.00" << endl;
cout << "Do you want to play <y/n>" << endl;
cin >> answer;
int flip = rand() % 3;
guess = flip;
while (toupper(answer) == 'Y')
{
cout << "Your bank is $" << bank << endl;
cout << "Enter heads or tails <h/t>" << endl;
cin >> guess;
while (guess == h)
{
bank++;
cout << "Winner, the flip came up " << flip << endl;
cout << "Would you like to play again <y/n>?" << endl;
cin >> answer;
}
}
return 0;
}
its suppose to look like this
and these are the guidelines

Here goes
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main()
{
srand(static_cast<unsigned int>(time(0)));
char answer;
int bank=10;
char guess;
char result;
cout << "Welcome to the coin flip game. It cost a dollar to play." << endl;
cout << "If you guess correctly you will will $2.00" << endl;
cout << "Do you want to play <y/n>" << endl;
cin >> answer;
while (toupper(answer) == 'Y')
{
bank--;
cout << "Your bank is $" << bank << endl;
cout << "Enter heads or tails (h/t)" << endl;
cin >> guess;
if(rand()%2==1)
result='t';
else
result='h';
if(guess==result)
{
bank+=2;
cout << "Winner, the flip came up ";
}
else
cout << "Sorry, you lose. The coin flip came up ";
if(result=='t')
cout << "Tails" << endl;
else
cout << "Heads" << endl;
cout << "Would you like to play again (y/n)?" << endl;
cin >> answer;
}
cout << "Thanks for playing, your bank is $" << bank << endl;
return 0;
}
Good luck!

Since you put C++ as languange, I would strongly recommend you to review modern (C++11) random engines.
Here is a good sample
