Implement MID function

[Dexxter]

I need implement a MID function like this:

Mid(string,START,FINISH)

Thanks

[kedaman]

use strncpy

[jim mcnamara]

General idea:

char *mid( char *strDest, const char *strSrc, 
                           size_t count,size_t offset ){
        
        strncpy(strDest, *(strSrc+offset), count);
        return strDest;
}

I think the extra abstraction layer is unnessesary overhead

[jim mcnamara]

It is.

But he asked how to do it. So I did it. He's a VB programmer trying to learn C, obviously.

[kedaman]

yeah obviously, but i think we'd do him a favour suggest to learn the language instead.

[Dexxter]

Thanks for the example.

Yes, i am a Vb programmer, i try learn VC, is very versatile, but very hard to learn too.

Important lesson: VC and VC++ are not languages. VC++ is an IDE. C and C++ are languages.

As for mid: it's called substr in the string class.

#include <string>
#include <iostream>
using namespace std;

int main()
{
  string mystring("Hello, there!");
  cout << mystring.substr(3, 4) << endl;
  return 0;
}

Output:
lo,
