The three times that are important in the lifetime of a C++ program are -
a) Compile time
b) Link Time
- C++ is a compiled language
- A compiler takes source code you can read and write and transforms it into a different format (the machine language)
- The compiler may give error messages
- The compiled output is generally called an object file.
- Any program larger than a demo is made of several source files.
- Each source file is compiled, then the object files are linked together to create an executable file (exe).
- In some projects, you would create a library file instead of an exe, but that is for later.
- The linker also gives error messages if it can't link the object files.
- Finally you run the application
- There maybe runtime messages or dialogs from the operating system, or that you wrote yourself
