no matching function for call to `getline(std::ifstream&, char*&)'

[cplusplus123]

Hello, I'm new. I read the C++ tutorial, and I'm trying to make a test program where you type a file path and it prints out the text inside it.

I've got a few problems, I could solve them all, but I still have a problem and I searched through all the ways, and I could not find an answer.

20 C:\[path]\test.cpp no matching function for call to `getline(std::ifstream&, char*&)' 

So here's my test code:

#include <iostream>
#include <cstdlib>
#include <fstream>
#include <string>
using namespace std;

int main() {
    char* path;
    char* currentline;
    cout << "File path:" << endl;
    cin >> path;
    cout << "Reading:" << path << endl;
    system ("ping localhost -n 3 >nul");
    system ("cls");
    ifstream fileopen;
    fileopen.open (path);
    if (fileopen.is_open())
    {
         do {
             getline (fileopen,currentline);
             cout << currentline << endl;
         } while (fileopen.good());
         fileopen.close();
    }
    
    else {
         cout << "Could not read file, probably it does not exist." << endl;
    }
    cout << "---" << endl;
    cout << "Press any key to exit." << endl;
    system ("pause >nul");
    return 0;
}

The "wrong line" is marked in bold (line 20). I really don't know what I'm doing wrong...

And one last thing.. remember I'm new :P

The first "wrong line" is line 11. path points to some random place in memory. You're writing to that random place on line 11. You would have the same problem on line 20. currentline is pointing to some random place in memory.

Changing path and currentline to std::string types would be a step in the right direction.

16 C:\[Path]\test.cpp no matching function for call to `std::basic_ifstream<char, std::char_traits<char> >::open(std::string&)' 

Now I'm getting this.. I have no idea on what to do :x

Depending on the age of the compiler, you may need to do this:

    fileopen.open (path.c_str());

Thank you, it works now.
