How do I fix compiler errors in C++?

I'm getting a 'missing semicolon' error in my C++ code. What does that mean?

A 'missing semicolon' error means that you've forgotten to add a semicolon at the end of a statement. Check the line indicated in the error message.

I see! I fixed that, but now I'm getting an 'undeclared identifier' error. What should I do?

An 'undeclared identifier' error occurs when you try to use a variable or function that hasn't been declared. Make sure you've declared it before using it.

Got it! One more thing, I'm confused about the 'type mismatch' error. Can you explain?

A 'type mismatch' error happens when you try to assign a value of one type to a variable of another type. Ensure that the types are compatible.
