What are the types of errors that can occur during compilation?

Question

Aryan Kumar · Answer

During compilation, several types of errors can occur. Some of the common types of errors include:

Syntax errors: These are errors that occur when the compiler encounters invalid syntax in the code. Syntax errors can be caused by things like missing semicolons, unmatched parentheses, or incorrect use of keywords.
Type errors: These are errors that occur when the compiler detects a mismatch between the declared type of a variable or expression and the actual type used in the code. Type errors can be caused by assigning a value of the wrong type to a variable or passing arguments of the wrong type to a function.
Semantic errors: These are errors that occur when the code is syntactically correct and has no type errors, but still produces unexpected or incorrect results. Semantic errors can be caused by things like incorrect use of logical operators, incorrect order of operations, or incorrect implementation of algorithms.
Linker errors: These are errors that occur during the linking phase of compilation, where the compiler combines object files and libraries to produce an executable file. Linker errors can be caused by missing libraries or undefined symbols.
Runtime errors: These are errors that occur during program execution, such as division by zero or accessing an invalid memory location. Runtime errors are not caught by the compiler and can cause the program to crash or produce unexpected results.

Overall, understanding the types of errors that can occur during compilation is essential for effective debugging and troubleshooting of code.
