(i)

highest mark;

(ii)

lowest mark;

(iii)

total mark;

(iv)

average mark.

(d)

Describe how you would merge two or more table cells in Microsoft Word.

Show Solution

(a)

Iteration in programming means repeating steps, or instructions, over and over again until told to stop or until a particular condition has been met. This is often called a "loop"

(b)

(i)

Algorithm is a plan, a set of step-by-step instructions to solve a problem.

The three basic building blocks (constructs) to use when designing algorithms are:
1. sequencing
2. selection
3. iteration

(ii)

Algorithm for eating breakfast cereal

1. Put cereal in bowl
2. Add milk to cereal
3. Spoon cereal and milk into mouth
4. Repeat step 3 until all cereal and milk is eaten
5. Rinse bowl and spoon

Algorithm for making a sandwich

1. Get bread slices
2. Put on the first layer of filling (like cheese)
3. Add another layer of filling (like ham)
4. Put on the other slice of bread
5. Repeat the steps of adding fillings (step 2 & 3) until you have all the desired fillings on the sandwich

Algorithm for saying a number from 1 to 10

1. Say 1
2. Repeat saying the next numbers (2, 3, 4, 5, 6, 7, 8, 9, 10) until you reach 10

Algorithm for saying a number from 10 to 1

1. Say 10
2. Repeat decreasing the number by 1 and saying it until you reach 1
Thus: 10 - 1 = 9, say 9
            9 - 1 = 8, say 8
            8 - 1 = 7, say 7
            7 - 1 = 6, say 6
            6 - 1 = 5, say 5
            5 - 1 = 4, say 4
            4 - 1 = 3, say 3
            3 - 1 = 2, say 2
            2 - 1 = 1 say 1

Note: an iteration/loop must stop at a point in time when a condition is met otherwise there would be an infinite loop (never-ending repetition).

(c)

(i)

highest mark → =MAX(B2:B6) OR =MAX(B2, B3, B4, B5, B6)

(ii)

lowest mark → =MIN(B2:B6) OR =MIN(B2, B3, B4, B5, B6)

(iii)

Total mark → =SUM(B2:B6) OR =SUM(B2, B3, B4, B5, B6)

(iv)

Average mark → =AVERAGE(B2:B6) OR =AVERAGE(B2, B3, B4, B5, B6)

Note: the = must be there to obtain the mark. Excel functions and formulas start with equal to sign (=).

(d)

How to merge table cells in Microsoft Word

Method I

1. Select the cells you want to combine
2. Go to the "Layout" tab under "Table Tools" and click "Merge Cells"

Method II

1. Select the cells you want to combine
2. Right-click on the selected cells
