Copying the contents of a Char array to another char array.

Posted 05 January 2011 - 10:57 AM

Hey there everyone, I'm attempting to copy the contents of a char array to another char array. The issue is the array I'm attempting to copy the string literal to is just a bad pointer. I have no idea how to proceed! Here is a sample of my constructor that I'm using to do this:

	ListNode(const char* elements) : mPrev(0), mNext(0)
	{
		//Get the length of the string input into the constructor.
		int length = strlen(elements);
		//Assign enough memory to mNode to copy across the string.
		mNode = new char[length];
		//Copy across the new string.
		strcpy(mNode, elements);
	}

Is This A Good Question/Topic? 0

You need to leave space for the null terminator: length + 1.

This is C++, so use a std::string and get on with life.
