Chapter 8 - Programming (IGCSE Computer Science)

What is a variable?

• A special character or word in a programming language that identifies an action to be performed

• A positive or negative whole number that can be used with mathematical operators

• A named data store that contains a value that does not change during the execution of a program

• A named data store that contains a value that may change during the execution of a program

What is a constant?

• A named data store that contains a value that does not change during the execution of a program

• A special symbol or word in a programming language that identifies an action to be performed

• A named data store that contains a value that may change during the execution of a program

• A positive or negative whole number that can be used with mathematical operators

What is an array?

• A set of programming statements grouped together under a single name that can be called to perform a task in a program

• A positive or negative whole number that can be used with mathematical operators

• A data structure containing several elements of the same data type

• A variable or constant that is several characters in length

What is the main reason for using a procedure in programming?

• To save and retrieve data from a magical book

• To perform calculations using wizardry

• To declare, use, and manipulate different types of wands and spells

• To group spells together under a single spellbook that can be called to perform a task in a program

What is the main purpose of a function in programming?

• To group programming statements together under a single name that can be called to perform a task in a program

• To declare, use, identify appropriate data types for, read and write arrays with one and two dimensions

• To perform calculations using arithmetic operators

• To store data in a file and retrieve data from a file

What is the purpose of the MOD operator in programming?

• To find the magical remainder of a division

• To uncover the hidden quotient (whole number part) of a division

• To perform a mystical rounding of a value to a given number of decimal places

• To conjure a random number

What does the DIV operator do in programming?

• To generate a random number

• To round a value to a given number of decimal places

• To return the quotient (whole number part) of a division

• To return the remainder of a division

What is the purpose of the ROUND library routine in programming?

• To generate a random number

• To return the quotient (whole number part) of a division

• To return the remainder of a division

• To round a value to a given number of decimal places

What is the purpose of the RANDOM library routine in programming?

• To return the remainder of a division

• To generate a random number

• To return the quotient (whole number part) of a division

• To round a value to a given number of decimal places

What is the purpose of the AND operator in programming?

• To perform logical AND operation on two boolean values

• To combine two numbers together

• To multiply two numbers

• To divide two numbers
