How do I get the user name of the current user?

Question

I want to access the user name in the Windows using C programming and use that name to create the path to the particular file like \"c:\\users\\john\\Roaming.....and so on\"

Answer 1

#include  

int main(void)
{
    printf("%s\n", getenv("USERPROFILE"));  // Print user's home directory.
    return 0;
}

To get the user name instead of the home path replace USERPROFILE with USERNAME.
