Question

hi! can someone tell me the difference between:

.cc

.h

and .o files and what goes inside each files for c++?

Answer 1

In the cc files have the source code of c++ program . That program(cc) may be refer(reference) by second program.We can open that cc file in various text editors ..cc is the file extension of a source code (file) of a program

Header file have an extension (.h). .h header contains C++ function declaration and macro definition.Header files contain definitions of Functions and Variables, which is imported or used into any C++ program by using the pre-processor #include statement. Every header file contains information or declarations for a particular group of functions. stdio.h header file for declarations of standard input and output functions available in C++ . That are used for get the input and print the output. Same as  the header file math.h is used for declarations of mathematical functions available in C++.There are 2 types of headers in c++ ie. System header files: It is comes with compiler and User header files: It is written by programmer.

.o object file file contains compiled object code. Object code is the machine code produced by your C or C++ compiler.Together with the names of the functions and other objects the file contains. Object files are processed by the linker.That produced file is the final executable file . If your build process has not produced these files, there is probably something wrong with your make file or project files.
