Moving the input file with c++ - c++

Question

I want to be able to enter any file in MoveFile() and it will move the file to this folder: C:\folder\fl.txt. When I enter MoveFileA("C:\\fl.txt", "C:\\folder\\fl.txt"); Then everything works, but I need to move the first file (the one that is fl.txt) to folder ...
How can this be implemented so as not to always enter the file name (C:\folder\fl.txt) so that it auto inputs it?
Here is my code:
#include <iostream>
#include <string>
#include <Windows.h>
#include <stdio.h>
#include <cstdlib>
using namespace std;
int main() {
MoveFileA("C:\\fl.txt", "C:\\folder\\fl.txt");
cout << "Operation Succesful" << endl;
cout << endl;
system("pause");
}
I need something like:
int main() {
int path_a;
cin >> path_a;
MoveFileA("path_a", "C:\\folder\\path_a");
cout << "Operation Succesful" << endl;
cout << endl;
system("pause");
}

Perhaps you are looking for something like this:
#include <iostream>
#include <string>
#include <cstdlib>
#include <Windows.h>
using namespace std;
int main() {
string filename;
cin >> filename;
if (MoveFileA(("C:\\"+filename).c_str(), ("C:\\folder\\"+filename).c_str()))
cout << "Operation Successful" << endl;
else
cout << "Operation Failed" << endl;
cout << endl;
system("pause");
}
Though, if you are using C++17 or later, you might consider a pure C++ solution using std::filesystem::rename() instead of the Windows-specific MoveFileA() function, eg:
#include <iostream>
#include <string>
#include <filesystem>
#include <system_error>
#include <cstdlib>
using namespace std;
namespace fs = std::filesystem;
int main() {
fs::path filename;
cin >> filename;
fs::path root("C:\\");
error_code ec;
fs::rename(root / filename, root / "folder" / filename, ec);
if (ec)
cout << "Operation Failed" << endl;
else
cout << "Operation Successful" << endl;
cout << endl;
system("pause");
}
