Compiling C++

To run any C++ code, it must first be compiled.

To do this, in terminal, cd to the desired directory and run g++ <path_to_file> -o <name_of_file_to_create>.

This will generate a new executable file, based on the compiled code.
Run this file via ./<name_of_created_file>.

For further details of how the compilation process works, see Compiling Code.

Types of Errors

• Compile Time Errors - Errors that happen during file compile.
  • Syntax Errors - Errors that happen from incorrect typed syntax for the given language.
  • Type Errors - Errors that happen due to mismatch of declared type and attempted type usage.
• Link Time Errors - Errors that happen when trying to combine compiled files into a single executable program.
  • Ex: Using a function that was never defined, or Main() instead of main().
• Run Time Errors - Errors that happen during program execution.
  • Ex: Divide-by-zero errors, or attempting to open a file mid-runtime and said file doesn't exist.
• Logic Errors - Soft errors that don't cause an actual crash. But can cause a program soft-lock, or general unintended behavior.
