nicktogo / Reverse Polish.cpp

Created March 10, 2017 12:41

The following code snippet is used toconvert an infix notation to a Reverse Polish notation and calculate it.

	void RPOUtil::Parse(TCHAR* exp) { // exp is the right hand side of an math equation, such as "2x + sin(x)"
	int length = ::wcslen(exp);
	char* cexp = new char[length + 1];
	for (size_t i = 0; i < length; i++) {
	cexp[i] = exp[i];
	}
	cexp[length] = '\0';
	string str(cexp);
	Replace(str); // replace "sin", "cos", "tan", "log" with "s", "c", "t", "l" respectively
	length = str.length();
