Displaying External File Contents C++

[CJPowell27]

Hey guys, I'm currently trying to write a function that when it is

called, it will display everything that is within the file.  The same

program is writing to an external data file and the function for 

displaying the contents will basically read everything that has been

written to the file.  Frankly, I was not taught how to do file input and

output streams and its a miracle that I got the write out to work.  

Does anyone have any idea how I would read in and display 

everything?

Thanks in advance,

#include <iostream>
#include <fstream>
#include <sstream>

std::string readFile(std::string s){
	std::stringstream ss;
	std::ifstream inputFile(s.c_str());
	
	if(inputFile.good()){
		ss << inputFile.rdbuf();
	}
	
	return ss.str();
}

int main () {
  std::string fileContents = readFile("test.cpp");
  std::cout << fileContents << std::endl;
  
  return 0;
}

Thanks, I actually kept playing around with my code after posting and figured it

out and this was basically my result.  I forgot to say that I no longer needed help,

but the way you put it allows me to implement something like this in the future.
