#include is a way of including a standard or user-defined file in the program and is mostly written at the beginning of any C/C++ program. The #include preprocessor directive is read by the preprocessor and instructs it to insert the contents of a user-defined or system header file in our C/C++ program. These files are mainly imported from outside header files. The process of importing such files that might be system-defined or user-defined is known as File Inclusion. This preprocessor directive tells the compiler to include a file in the source code program. read less
