Chapter 6: Programming ExercisesΒΆ

1. Write a program that consists of a  **main()**
   function and one or more other functions.  One of the
   functions must be called  **void printLetter( char,
   short, char );** where the formal parameters are

   void printLetter( char symbol, short height, char letter );


    **symbol** is a character such as '*';
    **height** specifies the number of symbol characters
        that compose the height; and,
    **letter** specifies a letter of the alphabet.

   The  **printLetter()** function prints a letter with
   the height specified using the specified symbol.  For

   symbol = '*'
   height = '5'
   letter = 'c'

   the function will print


   The width will always be 7.  Make the program
   continuously prompt for the input of the above data
   until a -1 is input for the height.  This should be
   written using C++ syntax.

2. Write a program that will convert an unsigned integer
   number to its binary representation and print on the
   screen that binary representation.  This program should
   consist of a  **main()** function, which prompts for
   the input of an unsigned integer value from the
   keyboard, and a second function called
    **convertToBinary( char [], unsigned )**, which
   converts the unsigned argument passed to its binary
   form.  The character string holding the binary string
   is returned in an array that is passed as an argument.
   DO NOT assume the word length of the system, but
   determine the word length by obtaining the number of
   bytes in an integer and using 8-bits as representing a
   byte.  Declare the array for the storage of the binary
   image large enough to hold 32 bits.  Write the program
   using C++ syntax.

3. Write a program to encode a message using the following

   1.   Enter a message (allow up to 256 characters).
   2.   Use a function compress() to remove the spaces
        from the entered message.
   3.   Print out the ASCII codes for the message
        characters in groups of 10 separated by two
