Problem with strncat() function (newbie)

In my search to create a program to convert C++ strings into C chars, I came across this funtion.

Code:

char *strncat(char *string1, char *string2, size_t n) - Append n characters from string2 to stringl.

Here's what I had so far. This generates quite a few compile errors, and I'm not quite sure what I'm doing wrong, as although I'm a newb in C++, I know almost no C :0

Code:

#include <iostream.h>
#include <stdlib.h>
#include <lvp\string.h>

char StringToChar(String StringWord)
{

  char CharWord[50], AddOnChar;
  String OneLetterString;
  int Size, Counter;
  Size = StringWord.length();
  if (Size <= 50) {
    for (Counter = 1; Counter <= Size; Counter++) {
      OneLetterString = StringWord.substr(Counter,1);

      if (OneLetterString == "A")
        AddOnChar = 'A';
      else if (OneLetterString == "B")
        AddOnChar = 'B';
      else if (OneLetterString == "C")
        AddOnChar = 'C';
      else if (OneLetterString == "D")
        AddOnChar = 'D';
      else if (OneLetterString == "E")
        AddOnChar = 'E';
      else if (OneLetterString == "F")
        AddOnChar = 'F';
      else if (OneLetterString == "G")
        AddOnChar = 'G';
      else if (OneLetterString == "H")
        AddOnChar = 'H';
      else if (OneLetterString == "I")
        AddOnChar = 'I';
      else if (OneLetterString == "J")
        AddOnChar = 'J';
      else if (OneLetterString == "K")
        AddOnChar = 'K';
      else if (OneLetterString == "L")
        AddOnChar = 'L';
      else if (OneLetterString == "M")
        AddOnChar = 'M';
      else if (OneLetterString == "N")
        AddOnChar = 'N';
      else if (OneLetterString == "O")
        AddOnChar = 'O';
      else if (OneLetterString == "P")
        AddOnChar = 'P';
      else if (OneLetterString == "Q")
        AddOnChar = 'Q';
      else if (OneLetterString == "R")
        AddOnChar = 'R';
      else if (OneLetterString == "S")
        AddOnChar = 'S';
      else if (OneLetterString == "T")
        AddOnChar = 'T';
      else if (OneLetterString == "U")
        AddOnChar = 'U';
      else if (OneLetterString == "V")
        AddOnChar = 'V';
      else if (OneLetterString == "W")
        AddOnChar = 'W';
      else if (OneLetterString == "X")
        AddOnChar = 'X';
      else if (OneLetterString == "Y")
        AddOnChar = 'Y';
      else if (OneLetterString == "Z")
        AddOnChar = 'Z';
      else if (OneLetterString == "a")
        AddOnChar = 'a';
      else if (OneLetterString == "b")
        AddOnChar = 'b';
      else if (OneLetterString == "c")
        AddOnChar = 'c';
      else if (OneLetterString == "d")
        AddOnChar = 'd';
      else if (OneLetterString == "e")
        AddOnChar = 'e';
      else if (OneLetterString == "f")
        AddOnChar = 'f';
      else if (OneLetterString == "g")
        AddOnChar = 'g';
      else if (OneLetterString == "h")
        AddOnChar = 'h';
      else if (OneLetterString == "i")
        AddOnChar = 'i';
      else if (OneLetterString == "j")
        AddOnChar = 'j';
      else if (OneLetterString == "k")
        AddOnChar = 'k';
      else if (OneLetterString == "l")
        AddOnChar = 'l';
      else if (OneLetterString == "m")
        AddOnChar = 'm';
      else if (OneLetterString == "n")
        AddOnChar = 'n';
      else if (OneLetterString == "o")
        AddOnChar = 'o';
      else if (OneLetterString == "p")

      else if (OneLetterString == "q")

        AddOnChar = 's';
      else if (OneLetterString == "t")
        AddOnChar = 't';
      else if (OneLetterString == "u")
        AddOnChar = 'u';
      else if (OneLetterString == "v")
        AddOnChar = 'v';
      else if (OneLetterString == "w")
        AddOnChar = 'w';
      else if (OneLetterString == "x")
        AddOnChar = 'x';
      else if (OneLetterString == "y")
        AddOnChar = 'y';
      else if (OneLetterString == "z")
        AddOnChar = 'z';
    }
    *strncat(*CharWord, *AddOnChar, 1);
    //CharWord+=AddOnChar;
    cout << CharWord << endl;
  }
  cout << "Complete";
  getch();
  return(*CharWord);
}

Any help would be appreciated

Why are you making the task so lengthy? You are using the string.h header from the lvp library. This file is similar to what is used for Visual C++ strings in that it incorporates a c_str() function to handle such a conversion for you. Here is what I mean.

Code:

// using Dev-C++ 4.01
#include <stdio.h>
#include <stdlib.h>
#include <lvp/string.h>

int main(int argc, char *argv[])
{
    String MyString = "My Name is Bubba";
    char MyChar[50];
    strcpy(MyChar, MyString.c_str());
    cout << MyChar << endl;

    return 0;
}

There is not much else to it.

Thanks!! I'm fairly new to C/C++ and I haven't fully explored the libraries.. this was all I could come up with on my own :0
