Convert int to string using C++

The C++ string class has many advantages and I personally like using it whenever I deal with strings in my C++ programs. Often times I have an integer stored in an int variable which I would like to have represented in string form. This function gives a simple way to convert an int value to a string.

string IntToString(int intValue) {
  char *myBuff;
  string strRetVal;

  // Create a new char array
  myBuff = new char[100];

  // Set it to empty
  memset(myBuff,'\0',100);

  // Convert to string
  itoa(intValue,myBuff,10);

  // Copy the buffer into the string object
  strRetVal = myBuff;

  // Delete the buffer
  delete[] myBuff;

  return(strRetVal);
}

There are many other ways to do this same thing, so if you have another way which might work better, please share your method using the comment system below.
