error code: no matching function for call to

Question

I am trying to read the file and store it in an array.

Here's the part of code I am using to open the file:

int readFile(AccessRecord & file, Files & namesIn)
{    
    std::ifstream fin(file.fileName);
    if (fin.fail())
    return -1;
}

this is the new error I am getting when I go to compile:

[meg21allred@LinuxLab08 ~]$ g++ myAssign02.cpp
myAssign02.cpp: In function ‘int readFile(AccessRecord&, Files&)’:
myAssign02.cpp:72:35: error: no matching function for call to

‘std::basic_ifstream<char>::basic_ifstream(std::string&)’
std::ifstream fin(file.fileName);

if I just use std::cout << file.fileName;, it seems to print out the correct fileName but it doesn't like it when I put file.fileName into ifstream line

Literally just copied the error message into google. – Quimby May 05 '19 at 20:36 — Quimby, May 05 '19 at 20:36

It looks like you're using a very old compiler that doesn't yet support the ifstream constructor that takes a string, which was added to the C++ standard library in 2011. The old constructor took a const char* (an old-fashioned C-style string), so try:

std::ifstream fin(file.fileName.c_str());
