I am attempting to create a program that retrieves the current user's username on Windows using C++.
I tried this:
char *userName = getenv("LOGNAME");
stringstream ss;
string userNameString;
ss << userName;
ss >> userNameString;
cout << "Username: " << userNameString << endl;
Nothing is outputted except "Username:".
What is the simplest, best way to get the current username?
In case GetUserName(username, &username_len); doesn't work when using a char[] as storage, you should know that GetUserName could be a macro solved to GetUserNameW. If u worked with Windows API probably u know the difference between W and A. Using GetUserNameA would solve the problem if you're using char[] as buf
By using getenv() function:
char * user = getenv("username");
cout << string(user) << endl;
If you want to convert into string then use:
string userStr = string(user);
void funtions::_GetUserNameA()
char username[1024];
DWORD username_len = 1024;
GetUserNameA(username,&username_len);
std::cout <<"username:"<< username <<"\n";
