Just do this

#include <string>
#include <fstream>
#include <streambuf>

std::ifstream file("file.txt");
std::string str((std::istreambuf_iterator<char>(file)),
                 std::istreambuf_iterator<char>());

Then

str.c_str();

Is the array that you seek.

If you want to copy the full content of file into the char array, you dont need to do it line by line. You can just copy the full content of file

You can read entire file into the string with

std::ifstream in("FileReadExample.cpp");
std::string contents((std::istreambuf_iterator<char>(in)), 
std::istreambuf_iterator<char>());

And then you can use contents.c_str() to get char array
