Why we compile the code?

)To transform a program written in a high-level programming language from source code into object code. Programmers write programs in a form called source code. … The final step in producing an executable program — after the compiler has produced object code — is to pass the object code through a linker.

Is GCC and Clang the same?

Gcc and Clang are pretty much the same from an end user perspective. Sometimes one produces better code, sometimes the other. Sometimes one compiles faster, sometimes the other. Each supports some minor subsection of the C++ standards that the other does not.

Should I use GCC or clang?

Clang is much faster and uses far less memory than GCC. Clang aims to provide extremely clear and concise diagnostics (error and warning messages), and includes support for expressive diagnostics. GCC’s warnings are sometimes acceptable, but are often confusing and it does not support expressive diagnostics.
