Insert one string of characters into another string

hello, i'm having problems writing a function for this scripit.

CPP / C++ / C Code:

void vowels(char string[])
{
       int i = 0;
        char c;
       while ((c = string[i++]) != '\0')
          switch(c)
          {
                 Case 'a':
                 case  'e':
                 case 'i':
                 case 'o':
                 case 'u':
             cout << c;
}  //end of switch
cout << endl;

return;
}

It asks to write af unction call addchar () to insert one string of characters into another string. The function should take three arguments: the string to be inserted, the original string, and the position in the original string where the insertion should begin. For example, the addchar("for all", message, 6) should insert the characters for all in message starting at message[5]

CPP / C++ / C Code:

void Insert( char* StringToBeInserted, char* OriginalString, int InsertionPosition)
{
  int i;

  // Make a buffer for building the new string
  char* buffer = new char[strlen(StringToBeInserted) + strlen(OriginalString) + 1];
  
  // put the first part of the OriginalString into the buffer
  for(i=0;i<InsertionPosition;++i) buffer[i] = OriginalString[i];

  // put the StringToBeInserted into the buffer now
  for(i=0;i<strlen(StringToBeInserted);++i) buffer[i + InsertionPosition] = StringToBeInserted[i];

  // put the last part of the OriginalString into the buffer
  // YOU CAN DO THIS PART

  // put the null terminator on the end of the string
  buffer[strlen(StringToBeInserted) + strlen(OriginalString)] = '\0';

  // copy the buffer back to the OriginalString
  // YOU CAN DO THIS PART

  // delete the buffer
  delete[] buffer;
}
