String Concatenation

[The Dark Knight]

Someone asked me how to do this, so I made a little program.

Contains the Compiled EXE and the Source Code if you want to study it.

Why not just use the standard C functions strncpy and strncat? Or better yet, use C++ standard strings instead of C char arrays:

#include <iostream>
#include <string>

using namespace std; // for simpilicity in example only, I would not usually use this

int main()
{
string str1;
string str2;
string str3;
cout << "Enter First String : ";
getline(cin, str1);
cout << "Enter Second String: ";
getline(cin, str2);
str3 = str1 + str2;
cout << "Concatenated String is : " << str3 << endl;
cin.get();
return 0;
}

Advantages:
No array bounds to worry about, so it's impossible to enter too large of a string (until you run out of system memory)
No special functions for copying and concatenating, just use + and =
Easy to use additional built-in functions, like for searching and parsing strings

Should work in any modern C++ compiler

The person wanted to see the logic of the entire thing and arrays.

It's the beauty of old school programming, it requires thinking.
