C++ Do while loop condition not working - c++

Question

#include<iostream>
#include<ctime>
#include<cstdlib>
using namespace std;
int main(){
int gnumber, rnumber;
char choice;
int tries;
do {
cout << "Welcome to the Number Guessing Game!" << endl;
cout << endl; // breakline
cout << "How many tries: ";
cin >> tries;
cout << endl;
while (tries > 0){
srand(time(NULL));
rnumber = rand() % 99;
cout <<"Enter an integer greater than or equal to 0 and less than 100:";
cin >> gnumber;
system("cls");
if (tries != 1){
if (gnumber < 100 && gnumber >= 0){
if (gnumber == rnumber){
cout << "Congratulations! You've guessed the number." << endl;
tries--;
cout << "Remaining tries: " << tries << endl;
}
else if (gnumber > rnumber){
cout << "Your guess is higher than the number." << endl;
tries--;
cout << " Guess Again!" << endl;
cout << "Remaining tries: " << tries << endl;
}
else{
cout << "Your guess is lower than the number." << endl;
tries--;
cout << " Guess Again!" << endl;
cout << "Remaining tries: " << tries << endl;
}
}
else
cout << "Must greater or equal to 0 and lesser than 100!" << endl;
}
else
{
cout << "Game over!" <<" The number is: " << rnumber << endl;
cout << "Play Again? (Y/N)" << endl;
cin >> choice;
system("cls");
}
}
}while(choice == 'Y' || choice == 'y'); //
system("pause");
return 0;
}
EVEN IF I ENTER CHOICE AS 'N' OR 'n' IT WONT STOP THE LOOP.
And even if I enter 'Y' or 'y', it does not ask how many tries i wanted.
Instead it just asks directly what integer I would want to enter.
Please try to copy and compile the code to further understand what the problem is. Please help.
P.S.: This is a guessing program I'm making by the way...

Answer 1

the bug in your inner loop if the use enters a value other than one in else you don't decrement tries so it gets stuck:
else
{
cout << "Game over!" <<" The number is: " << rnumber << endl;
cout << "Play Again? (Y/N)" << endl;
cin >> choice;
system("cls");
tries--; // add this
}
