1. Answer all questions list cd below: -

A) Using nested for loops.write the pseudocode segment that will display the following:~.

-J.: * *

B) A C program contains the following dcclarntious: -

f16at mo, yz, rt;int x , y, z :

Write a single C statement EA.CH that will:

i. accept user-input values for y and yz

II. increase mo by a quarter of 1110

iii. print the rt as a currency value in the format: $999999.99

IV. use the couditional rpcrlltqr 10 assign y to x if mo is positive; but assign z to x ifmo is not positive.

2. [C code Analysis]

Consider the following program solution written in C.

ftinclude <stdio.h>void main(void){

int year;int popl;const int curryear = 2012;printf ("Please enter the current population:");scanf ("%d", &popl);printf ("YEAR POPULATION\n=======================\n\n") ;for (year = 5; year> 0; year -= 1){

printf ("%4d %06d\n", (curryear - year), popl);popl += popl % year;

A) Using a Trace Table, show the contents of each variable & what will be displayed by the

above program if the user enters: 23 as tile current population.

3. [Decision Tables]

"Employees at Greggs Ltd work a set number of hours related to the following: All female

workers work for 5 hours a day as long as their salaries are below $ 15,000.00. All male workers

work for 5 hours a clay. Anyone with salaries above $60,000.00 must work on weekends. All

males with salaries equals to or less than $GO,OOO.OO get a maximum of7 hours overtime. Any

worker with salaries bet ween $15,000.00 and $60,000.00 (inclusive) also get a maximum of 7

hours overtime."

A) Construct a decision table, simplifying the conditions and outcomes to be used in the

above program's design.

problem? Justify the reason for the formula used for your answer.

4. [Pscudocoi\cl

A dating service wants to be able to find matches For its customers. They have commissioned

YOIl to build a system that will match customers based On the following information:

• NOTE; The company wants the program to calculate and output the 101;11

numhcr of compatihle matches that were made below.

• First, prompt the user for the total number of records to be processed.

• For each record to be processed, YOII should accept the custumcris gender, agc

and hcight.

, The system must validate the gender to make sure that it is only 'M' or '1"'. Ifthe

gender is not valid then an appropi-iate errnr message must be printed, assign

'F' to the variable and then continue with the rest of the system.

• The system must validate the age to make sure that it falls within the range ofln

to 60 (inclusivev. If the age is not valid then an ,lpprnprio,lc er'rnr mcssagc must

be printed, assign 60 to the variable ami then continue with the rest of the system.

" The system must then accept a customer's gender, ilgc and height from the user.

Assume that the entered information is valid.

• The system must then displuy an appropriate message stating whether the

inputted customer is compatihle or incomputihle with the record ill the database.

Customers are compatible as long as they have different geuners; their heights

are within l' (one foot) of each other; and their ages are the same.

Write the pseudocode corresponding to the design requested by SOM8.

5. [Fluwchart]

A) Design the flowchart that uses a loop to display all of the multtples of a variable ~

between vnriubles Y and z (inciusivei. (Declare any variables needed before use)

For example: x = 3,J' = 4, Z = 12; output is: 6 9 12

and prints out the slim or all squares from I to (and including) the integer. (Declare

allY variables needed before lIse)
