How To Parse String File Txt Into Array With C++

Question

I am trying to write a C++ program, but I am not familiar with C++. I have a .txt file, which contains values as follows:

0
0.0146484
0.0292969

First you'll need a vector:

std::vector lines; // requires #include 

Then you'll need to take a string taken from the getline operation, and push it back into the vector. It's very simple:

for (std::string line; std::getline(myReadFile, line);) 
{
    lines.push_back(line);
}

For an output operation, all you need is:

{
    int i = 0;

    for (auto a : lines)
    {
        std::cout << "lines[" << i++ << "] = " << a << std::endl;
    }
}
