Errors begin on line 34. Look up how the conditional operators work and what exactly the ; means in C++.

Your code reminds me of python :)

In C/C++ you need to wrap statements with { } if you want them to execute together.

as sasauke says, your error begins at line 34. I recommend reading about statements and flow control here. Compare the example if statements with your own.
