how to create a string from a txt file

Question

I am attempting to take a txt file and create a string from it but I cannot figure out how to make it work.

I have tried to use the getline string function but it does not create a proper string in the way I have used it.

ifstream inFile("somefile.txt");
string mystring;

while (getline(inFile, mystring)) {

    cout << mystring << endl;
}

The end goal of my program is to read a .txt file line by line and edit each line so it is 100 char wide. This first part seems to be the only place where I am having an issue at the moment.

This can be due to the stream object could not find or open the file. Try checking if the inFile is good or valid.

#include <iostream>
#include <string>
#include <fstream>
using std::cout;
using std::ifstream;
using std::string;
using std::endl;


int main() {
    ifstream inFile("example.txt");
    string mystring;
    if( inFile ) // or inFile.good()
    {
        while (getline(inFile, mystring)) 
        {
            cout << mystring << endl;
        }
    }
    else
    {
        cout << "Could not open File\n";
    }
    return 0;
}
