    Equivelatn function for sting.erase(..)

    I cant use string in a DLL as it crashes (discussed in a specific article)

    So I have to make my own erase function taht works like the strings one. Get it now?

    You just need a wrapper function around the string::erase method.

    Try something like:

    Code:
    char* serase(const char * s, int pos, int n);
    {
      static string str(s);
      str.erase(pos, n);
      return str.c_str();
    }
    Notice that I have made the strng object static. This is important in maintaining the persistence of the return result.

    Alternatively, you copy the result into a string pointer passed by argument.


    Correction:

    I think you may be better doing this, because of the static nature of str.

    Code:
    char* serase(const char * s, int pos, int n);
    {
      static string str;
      str = s;
      str.erase(pos, n);
      return str.c_str();
    }

    Why not just use memset()?

    char myString[32];
    strcpy(myString, "Hello World!");

    cout << myString << endl;
    memset(myString, 0, strlen(myString));
    cout << myString << endl;
