It's an assignment. Are you sure that we're allowed to help you?

I know how to do that, but you have to learn too y'know.

http://www-ccs.ucsd.edu/c/string.html <--- it's a list of all <string.h> functions. It would help you a lot.

Very Happy

At least you have to tell us what have you done so far, and which particular area that you have got stucked. You shouldn't expect us to just post the code to you. I hope you don't get upset, but if we do post the code to you then we are NOT helping you. you know?

OK, I will give you some hints so you can give it a try first, then post the question if you have one later.

The assignment is about String manipulation.
String is store in an Array (of char).
Array has indexes that begin with 0, then 1, 2, 3 and so on. Hnece you can access each character in the string ot array by using '[]' operator.
The size of the array is equal to the length of the string plus one for Null Terminator.
Null terminator is represented by '\0'.

Hope this gives you some idea to begin with.

Sample Output#1
--------------------

Enter A String: Hello There

Hello There!erehT olleH

Sample Output #2

Enter A String: Let's go.

Let's go.og s'teL

============================================================

The following code is nearly there

[code]#include <string>
#include <iostream>

using namespace std;

int main(int argc, char** argv)
{
string s, s1;

if(argc>1){
s.append(argv[1]);
s1.append(argv[1]);
}
for( int i=0 ; i<s.length() ; i++ ){
s1[i] = s[s.length()-i-1];
cout<<i<<" "<<s1<<" <-- "<<s[s.length()-i-1]<<endl;
}
s.append(s1);
cout << s << endl;
}[/code]

Modify it to fit your requirement.[/code]
