Do-while loop wont work!

Could you elaborate on what doesn't work?

[MasterMathematician]

The program runs and all, but when the user enters "y" for choice, the program closes. And it doesn't repeat the program.

[giblit]

Move the return( 0 ); outside of the do/while loop. You are telling it to end the program and to send 0 to the operating system. Also please put code tags around your code.

Thank youu so much!! I was stuck on this for quite a while now.
i also need to to add up the scores. My teacher said it has to be like this.
Could you help me with that?

Welcome to Rock Paper Scissors!
Please enter r/p/s for your choice.
Player 1: r
Player 2: p
Player 2 wins, Paper covers Rock!
Player 1: 0 win(s), 1 loss(es)
Player 2: 1 win(s), 0 loss(es)
Play again? (y/n): y

[giblit]

create 4 variable then to keep track of wins/loses for each player.

Then at the end of your loop add one to winners wins and one to the losers loses. Then output the wins/loses each time before asking them to play again.

[MasterMathematician]

Could you tell me how to do that?
Like what variable would i use and what type?
(I'm sorry i dont know shit about what i'm doing)

[giblit]

int player1_wins = 0;
int player1_loses = 0;
int player2_wins = 0;
int player2_loses = 0;

then to increment

++playerx_wins/loses;

[MasterMathematician]

I just did that but it says the increment is an undeclared identifier?
I think i'll be needing step by step instructions. I really suck at this :p

[giblit]

dont use playerx_wins/loses replace that with who won and who lost each round. You will need if statements

if( player_one_wins ) ++player1_wins;

like that.

[MasterMathematician]

is that good?

[giblit]

You weren't supposed to copy/paste you were supposed to fill in the blanks...

Look at your code. You have if statements telling which player wins.

Say for example the first if statement is player 1 wins because he has rock and they have scissor. Then you will add one to player one wins and one to player two losses.

*You will need to use curly braces so you can put more than one statement in each if statement.
