String Class

**CanadianOutlaw** · 10-09-2001

I'm working with the String Class and I'm trying to get my program so that when you inpute a word it will outpute it in reverserse. ie. Test will cout tseT.

I can get it to work for the one word but I need to get it to work for a variety of words. To display each of the letters I use

First = Word.length()-1;
Next = Word.length()-2;
To take the certain letter in a certain position and then
cout << Word.substr(First,Length);
cout << Word.substr(Next,1);
to outpute the last and next letters (t and s).

What I am trying to do is create some sort of a loop that will first output what I have and then subtract one and then output again. I've tried a for loop, do while, and while. They didn't seem to work but I think its just cause I didn't use either of them right. I believe it would be a for loop, but if anyone can help me out and give me some clue on the loop that is all I need. I know where to place it and all.

Thanx

You can either use a for loop or STL reverse -

Code:

#include <iostream> 
#include <string>
#include <algorithm>	//for std::reverse

using namespace std;

int main()
{

	string name = "zen";
	int nLength=name.length();
	for(int i=nLength-1;i>=0;i--)
		cout << name[i];

	cout << endl;
	

	// ...or using std::reverse
	reverse(name.begin(),name.end());

	cout << name << endl;
	return 0;

}
