my game wont continue
im new to C++ and this is a practice i found in a book and im having an issue
the goal of the game is for the computer to hit 0 before the user by subtracting either 1 or 2 at a time
what it is supposed to do is take a number the user inputs and subtract either 1 or 2 from it
then allow the user to input a number and have the computer take that number from the total post it and then subtract another number

BUT it isnt accepting the users input for n to subtract from total what am i doing wrong

im really starting to doubt this book too lol

Code:

```#include <iostream> #include <stdlib.h> using namespace std; int main() {   int total, n;   cout << "Welcome to Hell. Wanna play?" << endl;   cout << " Pick a number any number I can handle it." << endl;   cin >> total;   while(true) {   if ((total % 3) == 2){   total = total - 2;   cout << "I'll take 2 whether you like it or not. =P" << endl;   } else{   total--;   cout << " I'm taking one mo ........a." << endl;   }   cout << " Only " << total << "left. Can you even count that high?" << endl;   if (total == 0) {     cout << " HAHAHA I WIN I WIN I WIN !!!!!!!!!!!!!!!!" << endl;     break;     }     cout << "Pick a 1 or 2 I promise it doesn't matter though I'll still win  ";   cin >> n;   while (n < 1 || n > 2)     cout << "Hey I thought I told you 1 or 2 try again numskull " << endl;     cin >> n;     total = total -n;     cout << " Okay we are at" << total << " Good job you made me do the math for you now lets move on" << endl;     if (total == 0) {     cout << " Wow what a shocker you won. Good job you beat something that can't even think on its own" << endl;     break;         }   system("PAUSE");      return 0; }}```

Fix your indentation and you will spot the problem. More specifically, it is not right to end two scopes on the same line.

Perfect indentation is not a luxury, it is essential; a top priority when writing code. It's not something you fixup just when you feel like it. A real programmer has it right always.

well i haven't been taught anything about indentation and this book doesn't mention it im starting from scratch with 0 prior knowledge im just trying to do things that kinda make it easyer for me to read

But BURST, Malc just gave you a good advice. Read up on indentation. It's a little bit like when you write text, you follow certain rules to make the text readable. (Then on top of that you've got grammar, spelling etc.)

Thank you i worked on the indentation and found it >.<
but now im also trying to make this same program start itself over if the user wants it too

something like
Code:

```int again while (again == y){ cout << "do you want to play again (y/n)" << endl cin >> again; }```
but im not sure exactly how to put this into the code

this is what i have come up with but it doesnt work it asks for the first input to total then it just says press any key to continue what am i doing wrong?

Code:

```#include <iostream> #include <stdlib.h> using namespace std; int main(){     int total, again, n1, y = 1, n = 2;       cout << "Welcome to Hell. Wanna play?" << endl;     cout << " Pick a number any number I can handle it." << endl;     cin >> total; while ( again == 1){      while (total < 1) {     cout << " need a number greater then 0" << endl;     cin >> total;     }     while(total > 0) {         if ((total % 3) == 2){                 total = total - 2;                 cout << "I'll take 2 whether you like it or not. =P" << endl;         } else {                 total--;                 cout << " I'm taking one mo ........a." << endl;         }         cout << " Only " << total << " left. Can you even count that high?" << endl;         if (total == 0) {                 cout << " HAHAHA I WIN I WIN I WIN !!!!!!!!!!!!!!!!" << endl;                     break;     }     cout << "Pick a 1 or 2 I promise it doesn't matter though I'll still win  ";   cin >> n1;   while (n1 < 1 || n1 > 2){     cout << "Hey I thought I told you 1 or 2 try again numskull " << endl;     cin >> n1;     }     total = total - n1;     cout << " Okay we are at " << total << " Good job you made me do the math for you now lets move on" << endl;         if (total == 0) {             cout << " Wow whats a shocker you won. Good job you beat something that can't even think on its own" << endl;             break;             }         }  cout << " wanna go again? y/n" <<endl;  cin >> again;  }   system ("PAUSE");      return 0; }```
