Week 4 PRELIMS

Question 1

A visual lining tool. They can be used to represent an algorithm.

Answer 1

Flowchart

Question 2

The sequence of steps necessary to solve any problem.

Answer 2

Algorithm

Question 3

Indicates the starting point or stopping point in the logic. Every flowchart should start and end with this symbol

Answer 3

Terminal Symbol (Oval Shaped)

Question 4

Represents an input or output process in an algorithm, such as reading or writing output.

Answer 4

Input/Output Symbol (Parallelogram Shaped)

Question 5

Represents any single process in an algorithm, such as assigning a value or performing a calculation.

Answer 5

Process Symbol (Rectangle Shaped)

Question 6

Represents a module in an algorithm, that is, a predefined process that has its own flowchart.

Answer 6

Predefined Process Symbol (Rectangle Shaped with a line at each end of the shape)

Question 7

Represents a decision in the logic involving the comparison of two variables. Alternative paths are followed depending on whether the decision is true or false.

Answer 7

Decision Symbol (Diamond Shaped)

Question 8

Connects various symbols in a flowchart and contain an arrowhead only when the flow of control not fom top to bottom or left to right

Answer 8

Flowlines (A line with a Arrow Head at the end of it)

Question 9

What are the 5 Arithmetic Operators

Answer 9

(+) (-) (*) (/) (%)

Question 10

This operator adds its operands together.

Answer 10

Addition Operator

Question 11

This operator subtracts one operand from the other.

Answer 11

Subtraction Operator

Question 12

This operator divides the first operand by the second. Any remainder is dropped in order to return an integer value. If one or both of the operands are floating point values, the division operator performs floating point division.

Answer 12

Division Operator

Question 13

This operator (%) is informally known as the remainder operator because it returns the remainder after an integer division.

Answer 13

Modulus Operator

Question 14

It is used to increase an integer’s value by one, and it is used commonly in C++ operators.

Answer 14

Increment Operator

Question 15

What are the 2 forms of Increment Operator

Answer 15

Prefix
Postfix

Question 16

a form of increment operator that increments the value, and then proceeds with the expression

Answer 16

Prefix

Question 17

a form of increment operator that valuates the expression and then performs the incrementing.

Answer 17

Postfix

Question 18

It works in much the same way as the increment operator, but instead of increasing the value, it decreases it by one.

Answer 18

Decrement Operator (–)

Question 19

This operator assigns the right side to the left side.

Answer 19

Assignment Operator (=)

Question 20

What are the 4 Operators

Answer 20

Arithmetic Operators
Increment Operator (++)
Decrement Operator (–)
Assignment Operator (=)
