Thread: Not equal to operator NOT working

I have a question about the relational != operator.

First here is part of my code:

Code:

void RuleThree(string word, string target)
{
	string temp;
	int len = word.length()-1;   // Index of last character

	cout << target << endl;

	if (target!="TH" || target!="th")  // here is the problem!!

	{
		temp = word.substr(1,len);
		word = temp + target + "AY";
		cout << word << endl;
	}

} // End function RuleThree

This is simply not working. When my word starts with TH or th, it still accepts the word and goes through the code. When I do this though:

if (target!="TH" || target=="th")

where only one of them is set to not equal to, it works.

The problem is that I have to add more than just the TH and th to the if statement, but when I do, it treats it as an equal to.

I just don't get it.

Any help would be appreciated
