I am trying to write a program that can do postfix expressions in c++. First I have to read in the user input as a string. But how would I break up the string so I can tell whether each data is a number or a math operator? Please help me with this.
Code:int main()
{
string a;
getline(cin, a)
//How to break up the string into individual chunks for analyzing?
return 0;
}
