Getting Substring from class string object

[NabeelUsmani]

Is there a problem in my class getSubString Fuction.
there are two arguments taken (starting-index and length(that how big you want your substring to be))

"this is interesting." is calling object.
the main program takes the argument(start-index = 8, length = 11)

	int size = this->getLength() - startIndex;
	if(this->length == length)
		size = 1;
	int x = size <= length? size : length;
	char* temp = new char [x];
	int j = startIndex;
	for(int i=0; i<x; i++)
	{
		temp[i] = this->buffer[j];
		j++;
	}
	CMPT135_String ans(temp);
	return ans;

in my output it comes

interesting%%%%%%%%%%%%%%%%%%%%%%%%%%

** %% is represted as garbage.
I may be unclear with my question. Please ask

Hello NabeelUsmani,

Your bit of code looks like a function, but is it a stand alone function or part of a class? The function definition would be useful to see how he function parameters are used. Some indication of how the function is called would be helpful.

I really do not want to guess at the missing parts and get it wrong.

Hi Andy,

First there is a Class object made like s1 = "This is interesting ." then the function is called like s1.getSubString(8,11). The function above is a function of a class.

Thanks for your reply.

Hello NabeelUsmani,

What is "CMPT135_String" and how is it defined and where?

Trying to put together something I can test, but having trouble trying to figure out what is in your class.
