Thread: Storing Math expression as vector

okay so I have set up the following input which is a reverse polish notation expression that I need to turn to vector format to be used with an expression tree. Can anyone give advice? I am also wondering if what I have below is all I need actually.

Input:

Code:

std::string in = "3 5 12+25*/";

Function to change input string to vector form

Code:

int arithmetic_expression::inputRPN(std::string inputString)
{
    std::vector<std::string> expression = parse_string(inputString);

//not sure what needs to be done to make into vector here

You should loop through the string and push every character that isn't a space onto a std::stack. Just use a for loop and use the brackets to access each character individually.
