Explanation / Answer

1. Algorithm to swap the contents of two numbers

Algorithm:

Step 1: Start

Step 2: Read number1 and number 2

Step 3: Set temp = number1

Step 4: Set number1 = number 2

Step 5: Set number2 = temp

Step 5: Print number1 and number2

Step 6: Stop

2. Amount in PiggyBank

2 a. For this programming problem , how many outputs are required?

Answer: As per the question we will be given a certain amount of quarters, dimes, nickels and pennies and we need to calculate the total amount in dollars hence the program has only one output.

2 b. How many inputs does this problem have?

Answer: As per the question the PiggyBank contains quarters, dimes, nickels and pennies and hence the program requires 4 inputs.

2 c. Algorithm:

Step 1: Start

Step 2: Set totalDollars = 0

Step3: Read quarters

Step 4: Read dimes

Step 5: Read nickels

Step 6: Read pennies

Step 7: Compute totalDollars = totalDollars + (quarters * 0.25)

Step 8: Compute totalDollars = totalDollars + (dimes * 0.10)

Step 9: Compute totalDollars = totalDollars + (nickels * 0.05)

Step 10: Compute totalDollars = totalDollars + (pennies * 0.01)

Step 11: Print totalDollars

Step 12: Stop

2 d. Test the algorithm for 17 quarters, 24 dimes, 16 nickels and 12 pennies

Answer:

totalDollars =0

quarters = 17

dimes = 24

nickels = 16

pennies = 12

Now, totalDollars = 0 + (quarters * 0.25)

=> totalDollars = 17 * 0.25

=> totalDollars = 4.25

Now, totalDollars = totalDollars + (dimes * 0.10)

=> totalDollars = 4.25 + (24 * 0.10)

=> totalDollars   = 4.25 + 2.4

=> totalDollars   = 6.65

Now, totalDollars = totalDollars + (nickels * 0.05)

=> totalDollars = 6.65 + (16 * 0.05)

=> totalDollars   = 6.65 + 0.8

=> totalDollars   = 7.45

Now, totalDollars = totalDollars + (pennies * 0.01)

=> totalDollars   = 7.45 + (12 * 0.01)

=> totalDollars    = 7.45 + 0.12

=> totalDollars = 7.57

Hence we have a total of 7.57 dollars for the given input.

3. For the following algebraic expressions, write the corresponding c++ statements

a. (2)(3) + (4)(5)

The equivalent c++ statement is

(2 * 3) + (4 * 5)

b. 6 + 18

       2

The equivalent c++ statement is

(6 + 18) / 2
