使用可变目录在c ++中复制文件

Question

Basically I'm trying to copy a file from one place to another but I want the user to be able to change were to because its for a steam game and everyone has a diffident username.

system("copy GameMenu.res C:\\Program Files (x86)\\Steam\\steamapps\\"login"\\counter-strike source\\cstrike\\resource\\GameMenu.res");

In this line where it says "login" I want for people to be able to type their username and so it is still a part of the directory or whatever the thing is called. Please help me.

here is the code here is the whole code so you can see what's wrong with it:

#include <iostream>
#include <cmath>
#include <string>
int main ()
{
using namespace std;

string login;
int drive;

cout << "What is your steam login??" << endl;

cin >> login;

system("timeout 2");

system("cls");

cout << "Your files are being copied " << login << "." << endl;

system("copy GameMenu.res C:\\Program Files (x86)\\Steam\\steamapps\\"login"\\counter-strike source\\cstrike\\resource\\GameMenu.res");

system("pause");

system("cls");

system("timeout 1");

return 0;

}

Answer 1

You could prepare your String using concatenation for your login name problem and then convert it to const char * :

string str = "copy GameMenu.res \"C:\\Program Files (x86)\\Steam\\steamapps\\" + login + "\\counter-strike source\\cstrike\\resource\\GameMenu.res\"";
const char * c = str.c_str();

system(c);

Also as crashmstr mentioned in the comments, as you have spaces in your path you could have problems, so consider following his advice.
