c++ Fun

My proff. loves to use functions, so I use them mainly to keep him happy.

well, here's a clean version of the same program in 16 lines counting white spaces and looking pretty.

try it, then ask questions for any part of this you dont understand (or why i choose to do it this way instead of some other way)

Code: Select all


#include <iostream>
using namespace std;

int main()
{
   int numorig;
   cout << "Welcome to the square/cube program." << endl << "Please enter a number from 1-5 (any other number to quit): ";
   cin >> numorig;
   while (numorig >= 1 && numorig <= 5) {
      cout    << "Your number squared: " << numorig*numorig << endl
         << "Your number cubed: " << numorig*numorig*numorig << endl
         << "Please enter a number from 1-5 (any other number to quit): ";
      cin >> numorig;
   }

}


output looks like

Code: Select all


r000@ubuntu:~/stuff$ ./a.out

While I get what you are doing, and in the end its written better, the way I did my program was exercising the stuff from class that I know guarantees me a solid grade.

man I dunno what you did wrong with entering my code to get a bunch of errors...I just dropped it into my compiler and I got two...screwed up a variable name and had a 't' just sitting around.

Thought someone might enjoy this. Its comparing a simulation of comparing peoples birthdays in the room versus the mathematical probability. So birthday paradox simulation vs birthday paradox formula, and it really shows how weak the RNG of the function is . :

(5000 trials of the simulation btw)
