C++ file handling

Question

can we read and write .cpp files with file handling?

Answer 1

Yes, you can alter .cpp files using fstream.

Answer 2

No, as fstream only supports manipulation of files. It has no idea what the files are for and how are they to be used.

To compile a cpp file, you can use the system() function in <cstdlib>:

// C++ Version. Assuming C++11
string cpp_ver = "-std=c++11";
// Additional libraries which are required.
string libs = "";
// The file name, to be compiled.
// Provide Complete Path.
string file = "a.cpp";

system(("g++ "+cpp_ver+" \""+libs+"\" \""+file+"\ -o \""+file.substr(0,file.size()-5)+
"\"").c_str());

Answer 3

can we compile it also using file handling?
