Abstract
The purpose of this lab problem is to print the binary, hex, decimal, and ASCII values of the upper and lower case alphabet.
This problem will only work with the letters A through Z, upper and lower case.
The UPPER case letters will be converted to lower case by invoking the conversion function named ToLower. This function will only use bit manipulation to accomplish the conversion.
1 Objectives
1.1 Inputs
The only input is the name of the program myHexLetters. No other command line parameters are required.
1.1.1 Command Line arguments
The program will be invoked as follows:
- myHexLetters
2 Process
The program myHexLetters will generate and display the upper and lower case letters from A through Z. The conversion will be accomplished on a character basis using bit manipulations described in more detail below.
2.1 char ToLower(char myLetter)
Description: Converts the UPPER case letter to a lower case letter.
Returns: The lower case letter that was passed as input.
Caveat: The conversion must be accomplished using bit manipulation not addition or subtraction. That is the conversion must be accomplished using an AND, OR, XOR, or NOT operation as appropriate.
2.2 void printBinary(int someNum)
Description: Print the lower order 8 bits of an integer in binary.
Returns: Nothing.
Caveat: It is acceptable to use a loop over the 8 bits to determine if the bit under test is either a zero or a one. It is not acceptable to hard code the values of the 256 (or16) possible combinations.
3 Outputs
The output of the program will be for the upper & lower case letters A through Z. The outputs are shown below.

It is acceptable to print the output in a single column, that is for the upper case letters first, then the lower case letters.
