Programming aspects to get familiarized with:

Ø The use of decision structures

Ø The use of repetition structure.

A resistor is a circuit device designed to have a specificresistance value between its ends (see http://en.wikipedia.org/wiki/Resistorsfor more details on resistors). Resistance values are expressed inohms (?) or kilo-ohms (k ?). Resistors are frequently marked withfour colored bands that encode their resistance values, as shownbelow. The first two bands encode the first two significantdigits of the resistance value, the third is a power-of-tenmultiplier or number-of-zeroes, and the fourth isthe toleranceaccuracy, or acceptable error, of the value.

(Source: http://ikalogic.com/beg_1_res_v_c.php)

The table below shows the meanings of each band color. Forexample, if the first band is green, the second is black, and thirdis orange, and the fourth is silver, the resistor has a value of 50X 103 ± 0.1X50X103 ? or 50 ± 5k?.

The Challenge:

Design the algorithm for the software that prompts the user forthe colors of Band 1, Band 2, Band 3, and Band 4 and then displaysthe resistance in Kilo-ohms (C code is NOT accepted for thisquestion). Assume that band 4 can only be Gold or Silver.

a)       Present a main menu tothe user about the following options:

1)       Calculate resistancevalue

2)       Help

3)       Exit

The “help” option presents some information aboutthe program and how to use it, and re-displays the main menuoptions. The “Exit” option terminates the program. The“Calculate resistance value” leads the user to asecondary menu as shown in Step 2.

b)       The secondary menuprompts the user to select the band colors. For example:

1)       Black

2)       Brown

3)       Red

4)       Orange

5)       Yellow

6)       Green

.

.

Please select the color for band 1: 5

Please select the color for band 2: 0

Please select the color for band 3: 3

Please select the color for band 4: 11

The resistance value is: 50 ± 5 k?

Then the program should print back the main menu (Step 1).

Q1=> Make a program in C (.cfile)

Q2=>Write your report using the five steps model for softwaredevelopment :

a)       Step 1: ProblemIdentification and Statement

b)       Step 2: GatheringInformation

c)       Step 3: Test Cases andalgorithm

d)       Step 4: Code orimplementation

e)       Step 5: Test andVerification

f)        Step 6: Userguide
