Programming Principles

What can be used within programs and functions to organize different types of data in a computer program?

• Constants and variables

• Functions and arrays

• Loops and conditions

• Operators and expressions

What is a variable in the context of computer programming?

• A fixed memory location

• A set of instructions

• A named memory location where data can change

• A data type

How do we assign a value to a variable in a computer program?

• Using a comparison operator

• Using an assignment operator

• Using an arithmetic operator

• Using a logical operator

Which of the following is an example of changing the value of a variable during the running of a program?

• age = age + 1

• age == age + 1

• age + age = 1

• age = age

What is a constant in programming?

• A variable that can change during the execution of a program.

• A named location in memory that contains a value that does not change during the execution of a program.

• A function that performs a specific task.

• A data type that allows for different values over time.

When writing code, how are constants typically identified?

• By using lower case letters.

• By using a special symbol at the beginning.

• By using upper case letters.

• By using italics.

What is an array?

• A single value that can store multiple data types.

• A set of values of different data types stored under one identifier.

• A set of values of the same data type stored under one identifier.

• A function that stores multiple values.

What is the size and upper bound index of the array 'studentScores' as declared in the image?

• SIZE = 6, UB = 5

• SIZE = 7, LB = 0, UB = 6

• SIZE = 8, UB = 7

• SIZE = 7, LB = 1, UB = 7

How do you add a single value to an array?

• By calling a function with the array name and value.

• By assigning a value to a specific index of the array.

• By using a special array method.

• By redeclaring the array with the new value.

What will be the value of 'name1' after executing the code 'String name1 = studentNames[2];'?

• Charlie

• Oran

• Jason

• Jimmy
