Outputting the reversal of a string?

[Torm04]

Hello, I am having trouble with a certain part of my assignment. I am supposed to take strings from a .txt file and reverse the the order and then output it. I don't have much on this portion of the assignment but here is what I have.

#include <iostream>
#include <string>
#include <fstream>
using namespace std;
/////////------------------/////////
      //Function Prototypes//
	int fileLength();
	string reverseString();


/////////------------------/////////

int main()
{
	ifstream inFile;
	inFile.open("Chapter 10 C++ Text File.txt");
	
	string item;
	int count = 0;
	int length = 0;
	
	fileLength();
	reverseString();
	
	while(!inFile.eof())
	{
		inFile >> item;
		count++;
		length += item.length();
    } 

}

int fileLength() //Determines and returns the number of characters in the string.
{
	ifstream inFile;
	inFile.open("Chapter 10 C++ Text File.txt");
	
	string item;
	int count = 0;
	int length = 0;
		while(!inFile.eof())
	{
		inFile >> item;
		count++;
		length += item.length();
	}
		cout << "Length of characters in this file: " << length << endl;
}

string reverseString() //Outputs the string backwards
{
	ifstream inFile;
	inFile.open("Chapter 10 C++ Text File.txt");
	int count = 0;
	string item, reverse;
		while(!inFile.eof())
	{
		inFile >> item;
		count++;
		reverse += item;
	}
	cout << "Backwards: " << item  << endl;
	
}

Thanks for any help ^-^

Do you mean reverse the order of lines? Or reverse each individual line, but keep the order the same?

I would really like to reverse each individual line but keep the order the same.

This will return the reverse of it's argument.

string reverse_string(const string & original)
{
	string reverse("");
	for_each(original.rbegin(), original.rend(), [&reverse](auto c) {reverse += c;});
	return reverse;
}

Slightly shorter version of tipaye's.

string reverse_string(const string & original)
{
	return {original.rbegin(), original.rend()};
}
