Printing current file name with extension in C++ -

i writing c++ code , want print current filename extension. yes, it's 1 of asked questions. 1 solution use argv[0]. cool, it's not giving extension. can have extension?

you can print full path name using std::cout << __file__.

if want print file name alone, can do:

std::string file = __file__; size_t index; (index = file.size(); index > 0; index--) {     if (file[index - 1] == '\\' || file[index - 1] == '/')         break; } std::cout << file.substr(index);
