PDA Software I&T - Constructs Required

For this scenario which constructs do you need?

Scottish Athletics is running trials for 400 metre athletes. There are four groups of eight athletes. The runners run two separate laps and their times are recorded as they complete each of the two laps. Any runner who completes either of the two laps in under 50 seconds progresses to the next stage of selection. The runner from each of the groups with the fastest lap will receive a medal of commendation.  

 

Your task is:  

 

♦ to write a program for one of the groups of female runners  

♦ find the runners who will progress to the next stage  

♦ find the runner with the fastest lap  

 

Save this information to a file. You can assume that no two runners have the same name.

Which constructs are required for this scenario?

implement and test a program which will allow users to complete a survey about local facilities. The survey has 15 questions with different possible responses — some numerical answers and some text answers. Only one response is possible for each question. Every question has an option of ‘Do not know’. You should use a record structure to store details of the survey questions. There should also be an option in the program to calculate the total number of ‘Do not know’ responses.

Which constructs do you need for this scenario?

Implement and test a program to ask a user 10 addition questions using randomly created numbers between 10 and 30.  

 

The program should:  

 

♦ check if each of the user’s answer is correct  

♦ keep a total of the number of correct answers  

♦ repeat the quiz until the user achieves more than seven correct

WHich constructs are required for this scenario?

a program to assign grades to exam marks for a class of 15 students, using the following criteria:  

 

♦ more than 70% is an A  

♦ more than 60% is a B  

♦ over 50% is a C  

♦ more than 45% is a D  

♦ less than 45% is a fail  

 

The program requires the highest possible score for an exam, each student’s name (first name and surname) and each student’s mark.  

 

The program then:  

 

♦ calculates the percentage mark for each student  

♦ sorts the percentages into order from highest to lowest  

♦ displays each student’s initials, percentage and grade in the sorted order  

♦ displays the total numbers of As, Bs, Cs, Ds and fails

Which constructs are required for this program?

a program to calculate the number of points gained by five hockey teams, given the number of wins, draws and lost games, assuming a win is worth 3 points, a draw 1 point, and no points for a lost game.

Which constructs are required for this scenario?

program to enter and validate a password. The program should do the following:  

 

♦ Prompt the user to enter their password that can contain letters and numbers and be at least six characters long.  

♦ If the password is correct, it should display a welcome message.  

♦ If not, it should notify the user that their password was entered wrongly, they should be warned that they will be locked out of the system after three attempts and let them try again but only allow three tries.  

♦ If the user makes three incorrect attempts they should receive a suitable message.

Which constructs are required for this scenario?

a program which:

♦ Fills an array with 20 random integers between 1 and 10.

♦ Prints the array contents to screen.

♦ Finds and displays the maximum and minimum values in the array.

♦ Asks the user for an integer between 1 and 10 using input validation and displays how many times it occurs in the array.

♦ Asks the user for an integer between 1 and 10 using input validation and displays where in the array that number first occurs and indicates when it is not present.

Which constructs are required for this scenario?

a program to simulate a simple game. Your program should do the following: 

 

♦ Store six colours in an external file (Note: these colours can be your choice of words or graphics).  

♦ Create three arrays and input the colours to each of the arrays.  

♦ For each of the three arrays, create a random number between 1 and 6 and output that colour to the screen.  

♦ If two of the colours match, the user wins 50 pence.  

♦ If all three colours match, the user wins £1.  

♦ Allow the user to have five ‘shots’ and keep track of their winnings.  

♦ Display suitable messages on screen.
