C String Functions (cont.)

• possible implementation of strcpy()

void strcpy (char* str2, const char* str1)
{
  while (*str1 != '\0')
  {
    *str2 = *str1;
    ++str2;
    ++str1;
  }
  *str2 = '\0';
}

• Assumption that str1 is null-terminated used implicitly
• Assumption that str2 has been allocated sufficient memory used implicitly
• C string functions do not handle or "worry about" memory management
