PROMPT THE USER TO ENTER THREE INTEGER VALUES, A STARTING TEMPERATURE, AN ENDING TEMPERATURE, AND AN INCREMENT. A FTER THESE VALUES HAVE BEEN ENTERED THE PROGRAM WILL DISPLAY A TABLE OF EQUIVALENT C AND F ( OR F AND C) TEMPERATURES, FROM THE STARTING TEMPERATURE TO THE ENDING TEMPERATURE AND INCREMENTING BY THE INCREMENT VALUE EACH ROW. T HE TABLE MUST MEET ALL OF THE FOLLOWING CRITERIA : T HE TABLE ' S COLUMN HEADINGS SHOULD DISPLAY THE DEGREE SYMBOL, E. G., °C AND °F. T HE FIRST COLUMN MUST BE THE " FROM " TEMPERATURE (C FOR C TO F OR F FOR F TO C) AND THE SECOND COLUMN THE " TO " TEMPERATURE (F FOR C TO F OR C FOR F TO C). T HE CALCULATED " TO " TEMPERATURES ARE TO BE DISPLAYED TO THE NEAREST TENTH OF A DEGREE ( DISPLAY EXACTLY ONE DECIMAL PLACE, EVEN IF THERE IS NO FRACTIONAL PART, I. E., 75° SHOULD DISPLAY AS 75.0°). T EMPERATURES IN BOTH COLUMNS MUST BE NUMBER - ALIGNED ( RIGHT - JUSTIFIED FOR THE INTEGER " FROM " VALUES AND DECIMAL POINT ALIGNED RIGHT FOR THE " TO " VALUES ). A SSUME THE USER ENTERS CORRECT DATA, E. G., THE START TEMPERATURE, END TEMPERATURE AND INCREMENT ARE ALL INTEGERS AND THE ENDING TEMPERATURE IS GREATER THAN THE STARTING TEMPERATURE. T HE FORMULA TO CONVERT C ELSIUS TO F AHRENHEIT IS T HE FORMULA TO CONVERT F AHRENHEIT TO C ELSIUS IS F UNCTION R EQUIREMENTS Y OU MUST CREATE AND USE THE FOLLOWING FUNCTIONS : DISPLAY M ENU ( ) DISPLAYS A MENU.

A NY OTHER INPUT SHOULD GET AN ERROR MESSAGE "I NVALID SELECTION : TRY AGAIN " AND RE - PROMPT FOR THE MENU SELECTION.

A DDITIONAL R EQUIREMENTS A BSOLUTELY NO GLOBAL VARIABLES CAN BE USED TO IMPLEMENT THIS PROGRAM ! A NY PROGRAM USING GLOBAL VARIABLES WILL NOT BE ACCEPTED ! U SE A SWITCH STATEMENT TO RESPOND TO THE USER ' S MENU SELECTION IN THE GET M ENU S ELECTION FUNCTION. A FTER THE USER SELECTS A VALID TEMPERATURE TABLE OPTION, ASK THE USER TO ENTER START, END, AND INCREMENT VALUES, THEN DISPLAY THE TABLE AND STOP UNTIL THE USER PRESSES THE ENTER KEY TO CONTINUE ( PROMPT THE USER, OF COURSE ). W HEN THE USER PRESSES ENTER TO CONTINUE THE MENU SHOULD BE REDISPLAYED, ALLOWING THE USER TO MAKE ANOTHER MENU SELECTION ( EITHER TO DISPLAY ANOTHER TEMPERATURE CONVERSION TABLE OR QUIT ). M AKE SURE THAT YOUR CODE IS PROPERLY FORMATTED ( INDENTATION, ETC ) AND THAT YOU HAVE PROVIDED SUITABLE DOCUMENTATION OF ALL YOUR FUNCTIONS ( COMMENT BLOCKS FOR PROGRAM AND FUNCTIONS !). H OW TO PRINT THE DEGREE SYMBOL I T IS EASY ENOUGH TO FIND OUT HOW TO DO THIS BY SEARCHING THE WEB. T HE SHORT ANSWER IS : COUT T EST P LAN T EST CASES ARE GENERALLY SELECTED BY ANALYZING THE PROGRAM AND DETERMINING CATEGORIES OF INPUTS AND OUTPUTS, THEN SPECIFYING AT LEAST ONE SPECIFIC INPUT VALUE ( OR SET OF INPUT VALUES ) FOR EACH CATEGORY. I NPUTS FOR THIS PROGRAM INCLUDE THE " SELECTION," OR MENU INPUT, AND INTEGER VALUES TO GENERATE A TABLE ( START TEMPERATURE, STOP TEMPERATURE AND INCREMENT VALUE ). H ERE IS AN OUTLINE OF THE CATEGORIES : M ENU TEST CASES SHOULD INCLUDE ALL POSSIBLE VALID MENU SELECTIONS AND AT LEAST ONE INVALID MENU SELECTION. T ABLE TEST CASES SHOULD INCLUDE 2.1. I NPUTS THAT CREATE TABLES WITH VARIOUS NUMBERS OF ROWS 2.2. A T LEAST ONE TEMPERATURE THAT CALCULATES TO AN EXACT WHOLE NUMBER OF DEGREES ( E. G., 0 DEGREES DEGREES F) N EGATIVE STARTING AND ENDING TEMPERATURES A T LEAST ONE TEMPERATURE THAT CALCULATES TO A FRACTIONAL NUMBER OF DEGREES ( E. G., -50 DEGREES DEGREES C) S OME COMMON, EASY TO VERIFY CONVERSIONS, FOR EXAMPLE DEGREES DEGREES F ( AND VICE VERSA ) DEGREES DEGREES F ( AND VICE VERSA ) , THE ONLY TEMPERATURE THAT IS THE SAME IN BOTH. G IVEN THESE CATEGORIES, USE THE TABLE ON THE NEXT PAGE TO RECORD THE SPECIFIC INPUT VALUES YOU WILL USE FOR YOUR TEST PLAN. N OTE THAT YOU MUST PREDICT AND DOCUMENT WHAT THE OUTPUT WILL BE FOR EACH OF YOUR TEST CASES, INCLUDING THE CALCULATED VALUES FOR EACH ROW OF THE TEMPERATURE TABLES PRODUCED. T EST YOUR PROGRAM USING YOUR SELECTED TEST CASES AND RECORD THE ACTUAL OBSERVED OUTPUT FROM YOUR TEST CASES BY PASTING SCREEN SHOTS INTO YOUR REPORT DOCUMENT. M AKE SURE EVERYTHING WORKS CORRECTLY BEFORE SUBMITTING.
