What is computer program in c plus plus?

Answer 1

The C++ standard does not impose any extension rules on source code files. Conventionally, all C++ headers use a .h extension while all C++ source files use a .cpp extension, however you are free to choose your own extensions as you see fit. Some programmers prefer .hpp for C++ headers in order to differentiate them from C headers, however there's no requirement to do so unless you are specifically differentiating C-style headers from C++ headers. Similarly with .c and .cpp extensions with respect to C-style code and C++ code. In the main it's best to stick with the well-established conventions.

Answer 2

A computer program in C++ is a machine-code executable (EXE or DLL) that was originally written in C++, and subsequently compiled by a C++ compiler and linker.

Answer 3

Source program (usually referred to as source code) in C++, is the high-level code you write and subsequently compile to produce the native machine code that the computer can understand.
