Week 3 HW

###The Assignment

• Create a “Parser” Object and a main.cpp file to handle IO
• Must have 2 functions

  • Pyramids

    • Use Pointers! (if you can)

     #include <iostream>
     using namespace std;
     
     void pyramid(string* loc, int levels) {
     	std::string s = *loc;
     	s = "*\n**\n***\n****"; //no you can't do this, you gotta do it with for loops
     	//put code here (s+= "*") and etc, \n gives you a line break
     	*loc = s;
     
     }
     
     int main() {
     	string str = "";
     	string* strLoc = &str;
     	pyramid(strLoc, 3);
     	cout << str << endl;
     }
     
     			
     						

  • Reference

    • Must be able to take command line input
    • Example Usage

     ./program -h ->returns a list of commands
     ./program -h [Command] -> returns description of that command
     ./program -h nano -> returns "A terminal text editor (you can't use nano now)

Pick the three most useful commands (or more) to put into the data base
