***************I'm trying to make a rock paper scissors game. The game compiles fine, however it doesn't count the wins, losses, and ties correctly. How do I fix this? I'm a new programming and I'm sure there was a better way to construct this, but I just need the counter fixed. It needs to run until user exits, and then tally wins, losses, and ties :) Thanks! Please explain what I did so I can learn from it :)
Explanation / Answer
Here you go :)
Everything is fine except the wins++/loss++/tie++ in the if conditions.
They must be done when the two if conditions satisfy, you forgot to include the paranthesis (i've bolded them) and hence the mistake.
It can be solved in a better way though. As you are new to programming this is just fine.
