- High-level language programs are usually written (coded) as ASCII text into a source code file. A unique file extension (Examples: .asm .cob .for .pas .c .cpp) is used to identify it as a source code file. As you can guess for our examples – Assembly, COBOL, FORTRAN, Pascal, "C" and "C++" however, they are just ASCII text files (other text files usually use the extension of .txt).
- 5.2: Standard Input and Output
- Every task we have the computer do happens inside the central processing unit (CPU) and the associated memory. Once our program is loaded into memory and the operating system directs the CPU to start executing our programming statements the computer will begin executing the code.
- 5.3: Compiler Directives
- A compiler directive is an instruction to the compiler to complete a task before formally starting to compile the program, thus they are sometimes called pre-processor directives. Among other items, during the pre-processor step the compiler is looking for compiler directives and processes them as they are encountered.
