. We know that a program written in a compilation language such as C or C ++ can be converted from the source file to the machine language used by the computer, and a binary executable file is formed after the connector connection. When we run the binary executable program, because it has been compiled, the loader software loads the binary program from the hard disk into the memory and runs it. In contrast, a program written in
