Here is the first "homework". You can attempt this during your regular
lab time on Friday, or at any other time when you can find a spot in the
lab. A TA won't be there, but you won't need a TA.

Type the following lines of C++ code
using your favorite text editor. Call the program
simple.cc


//This is a simple C++ program

#include <iostream>
using namespace std; //Lets you use all symbols in the standard namespace
                     //such as cout without the std:: throughout your
                     //program
                     //Even if you take this out, the code will still work
                     //and you won't get any compile-time errors 
                     //with most C++ compilers

int main(){

  int i;
  int j;
  int z = 1;

  if (!z) {
    i = 0; 
    j = 0;
  }
  else
    if ( z > 0) 
      {
	i = 1; 
	j = 1;
      }
    else
      {
	i = 2; 
	j = 2;
      }

  cout << "i = " << i << ", " << "j = " << j << endl;
  return 0;

}  

Then type the following
command at the command prompt:

g++ -o simple simple.cc

Then type at the command prompt
simple 
to execute your program.

Look at the output

Attempt the following exercises:
Replace the !z conditional with z == 0 What happens ?
Replace the !z conditional with !(z != 0) What happens ?

Replace the !z conditional with !(z == 0) What happens ?

Try to reason about the output you get in each case and why you get it.
