Need help with my Tic tac toe

I believe your problems are here:

//line #78
if (currentPlayer ='X')

//and line #81
else (currentPlayer = 'O');

You are making a common mistake when it comes to boolean comparison.. take a minute, think about it, and tell us what ye' come up with.

In fact this error is so common, I believe compilers should throw warnings whenever this is detected.

[manofhouse]

If your talking about the semi colon I have already tried removing it and the code wouldn't run

[Clinton Portis]

I have never seen an assignment operator in boolean if/else logic... ever.

I have only seen boolean operators, such as: <, >, <=, >=, ==, !, && and ||.

And yes, that semicolon should not be there.

[macobex]

also, i think there is no such statement as

else (CONDITION)

it must be

else {
 // code here
}

or

else if (CONDITION) {
  // code here
}
