what is g++ and gcc
GCC stands for GNU Compiler Collections which is used to compile mainly
C and C++ language. It can also be used to compile Objective C and Objective
C++. The most important option required while compiling a source code file is
the name of the source program, rest every argument is optional like a
warning, debugging, linking libraries, object file, etc. The different
options of GCC command allow the user to stop the compilation process at
different stages.
g++ command is a GNU c++ compiler invocation command, which is used
for preprocessing, compilation, assembly and linking of source code to
generate an executable file. The different “options” of g++ command allow
us to stop this process at the intermediate stage.
