Prgramming (flowcharts And Pseudocode)

Question 1

What is meant by a data type?

Answer 1

A data type specifies the value a variable can hold. And determines the range of values and operations performed on the variable.

Question 2

What are some examples of data types?

Answer 2

Integer: Represents whole numbers (e.g., 5, -10).
Real (Float): Represents decimal numbers (e.g., 3.14, -0.5).
Boolean: Represents true or false values.
Character: Represents a single character (e.g., ‘A’, ‘x’).
String: Represents a sequence of characters (e.g., “Hello, World!”).

Question 3

What are constants and variables?

Answer 3

Constants- fixed values that don’t change in the program (π}
Variables- Named memory locations that can hold different values during program execution.

Question 4

What’s iteration?

Answer 4

Iteration refers to repeating a set of instructions a certain number of times or until a condition is met.

Question 5

State the types of iteration:

Answer 5

a) Definite (Count-Controlled) Iteration: Executes a fixed number of times (e.g., using loops like for or while).

b) Indefinite (Condition-Controlled) Iteration: Repeats until a specific condition becomes false (e.g., using while loops).

Question 6

What’s selection?

Answer 6

Selection allows the program to choose between different paths based on a condition (usually using if, else if, and else statements).

Question 7

What are nested structures?

Answer 7

involve combining multiple control structures (e.g., loops and conditionals) within each other. For example, an if statement inside a while loop.

Question 8

Why are meaningful identifiers important?

Answer 8

Correct naming of variables, constants and program elements enhance code readability.

Instead of using vague names like x, opt for more descriptive identifiers (e.g., total_sales).
