What are some common compile-time errors in C++?

Common compile-time errors in C++ include syntax errors, type mismatches, and undeclared identifiers.

Can you give me an example of a syntax error?

Sure! A syntax error can occur if you forget a semicolon at the end of a statement, like this: 'int a = 5'.

What happens if I try to use a variable that hasn't been declared?

If you use an undeclared variable, the compiler will throw an error indicating that the variable is not defined.

How can I fix type mismatch errors?

To fix type mismatch errors, ensure that the variable types are compatible with the operations being performed.
