Which type of error is usually detected during the compilation of a program?

A syntax error is a type of error that occurs when the code violates the grammatical rules of the programming language. These mistakes can include missing semicolons, incorrectly placed brackets, or misspelled keywords. Since these errors result in code that cannot be interpreted correctly by the compiler, they are typically identified during the compilation process before the program even runs. This allows the programmer to fix the syntax issues before execution.

In contrast, logic errors occur when the program runs but produces incorrect results due to flaws in the algorithm or logic. These are not detected at compile time and are usually found through testing. Runtime errors happen while the program is executing, often due to operations like dividing by zero or trying to access invalid memory. Load errors typically refer to problems that arise when trying to load a program, which are different from syntax issues altogether.
