What does Pragma once do C++?
In the C and C++ programming languages, #pragma once is a non-standard but widely supported preprocessor directive designed to cause the current source file to be included only once in a single compilation.
What is the difference between g ++ and C++?
g++ is the gnu c++ compiler where c++ is the system c++ compiler, in the case of ubuntu C++ is a link to g++ however in another system it could very well be a link to a non gcc compiler.
Is GCC a compiler?
GCC is portable and run in many operating platforms. GCC (and GNU Toolchain) is currently available on all Unixes. They are also ported to Windows (by Cygwin, MinGW and MinGW-W64). GCC is also a cross-compiler, for producing executables on different platform.
Does G ++ support pragma once?
Most modern and relevant compilers support it, at least VC++, g++, clang, Intel. To be on the safe side, you should still prefer the classical header guards — #pragma once is not C++ standard, and no compiler is forced to support it.

Should I use Pragma once or Ifndef?
#pragma once is shorter than an include guard, less error prone, supported by most compilers, and some say that it compiles faster (which is not true [any longer]). But I still suggest you go with standard #ifndef include guards.

The compiler also ensures that your program is syntactically correct. … The compiler we use is the GNU (Gnu is not Unix) Open Source compiler. G++ is the name of the compiler. (Note: G++ also compiles C++ code, but since C is directly compatible with C++, so we can use it.).
Should I use GCC or G ++?
When referring to C++ compilation, it is usual to call the compiler “G++”. Since there is only one compiler, it is also accurate to call it “GCC” no matter what the language context; however, the term “G++” is more useful when the emphasis is on compiling C++ programs.

Writing the compiler in X; then hand-compiling it from source (most likely in a non-optimized way) and running that on the code to get an optimized compiler. Donald Knuth used this for his WEB literate programming system.
