"use shell symbols in directory path" Code Answer

You can use wordexp:

#include <wordexp.h>

std::string wordexp(std::string var, int flags = 0)
{
    wordexp_t p;
    if(!wordexp(var.c_str(), &p, flags))
    {
        if(p.we_wordc && p.we_wordv[0])
            var = p.we_wordv[0];
        wordfree(&p);
    }
    return var;
}

int main()
{
    std::cout << wordexp("~/test") << 'n';
}
