示例1: removeBlockComments

//Remove all block comments from the tokenList including /* and */ markers
//Returns the number of block comments removed (where each pair of /* and */ count as one comment)
int removeBlockComments(TokenList &tokenList) {
	//this funtion deletes the block comments in the tokenlist
	int count = 0;
	bool deleted = false;
	Token* temp, *destroy;
	temp = tokenList.getFirst();
	while (temp) {
		//loop check if list is empty
		deleted = false;
		if (temp->getStringRep() == "/*") {
			//upon finding a block entry comment you keep deleating tokens till you find the exit token
