c++ - How to copy a file from a folder to another folder

Question

How do I copy a file from one folder to another folder using C++?

Answer 1

This should be the minimal code required:

#include <fstream>

// copy in binary mode
bool copyFile(const char *SRC, const char* DEST)
{
    std::ifstream src(SRC, std::ios::binary);
    std::ofstream dest(DEST, std::ios::binary);
    dest << src.rdbuf();
    return src && dest;
}

int main(int argc, char *argv[])
{
    return copyFile(argv[1], argv[2]) ? 0 : 1;
}

it glosses around some potentially complicated issues: error handling, filename character encodings... but could give you a start.
