Answer 1

Answer:

Many programming languages and other computer files have a directive, often called include (sometimes copy or import ), that causes the contents of a second file to be inserted into the original file. These included files are called copybooks or header files.

Answer 2

Answer:

• Code from a supplied file is pasted into the current file using the preprocessor directive #include. It is used to include header files that are both system- and user-defined. A compiler error is produced if an included file cannot be found.
• A standard or user-defined file can be included in a C/C++ program by using the #include statement, which is typically written at the start of the program. When the preprocessor reads this directive, it is instructed to execute the following program with the content of a user-defined or system header file.
• The #include directive instructs the C preprocessor to start with the first portion of the original file and then include the contents of the file given in the input stream to the compiler.
