Homework 3

 

1. Identify which of the following are legal variable names.  For those that are not legal, indicate why.

  1. theUnitedStatesNavalAcademyIsLocatedInAnnapolis
  2. average CPR    
  3. class_Of_83               
  4. averageSum
  5. 7thCompany

 

2.   Copy and paste the following program into a new main.cpp and compile (use VMWare or putty or whatever you like to get access to a g++ compiler). 
Examine the errors generated by the compiler.  For EACH error reported by the compiler, circle the line causing the error, and indicate what would need
to be changed on the line in order to remove the error. 

 

// cents.cpp

// Convert nickels and dimes to cents.

#include <iostream>

using namespace std;

 

int main()

{

   int nickels, dimes, cents;

   nickels = 3;

   Dimes = 7;

   cents = 5 * nickels + 10 * dimes;

   cout << nickels << " nickels and ";

   cout << dimes << " dimes " << endl;

   cout << "= " << cents << " cents "

   return 0;

}

3. Using your favorite editor and compiler/linker fix each compiler error in question 2 above.   

Turn in: Printout this homework assignment and annotate with your answers to questions 1 and 2. For question 3, attach a printout of the source code for your program (e.g., the fixed main.cpp), and a screen capture of the window showing your program successfully compiling.  Note: to capture a screen image, click in the window you want to capture, press <Alt> <Printscreen>, and paste the picture into, for example, a Word document. If necessary, you can also use a screenshot to show the source code for your (corrected) program (or one screenshot that shows both the source code and the output). Finally, don't forget to also turn in the answers to questions 1 and 2.
