CrashCourse Computer Science Quiz

Why were programming languages developed?

• To increase hardware complexity

• To make computers faster

• To reduce the need for programmers

• To abstract away low-level details

What is syntax in programming languages?

• The user interface design

• The hardware configuration

• The set of rules for structuring statements

• The speed of the program

What does the statement 'A equals 5' signify in programming?

• A variable named A has the number 5 stored in it

• A is less than 5

• A is not equal to 5

• A is greater than 5

What is an assignment statement in programming?

• A statement that repeats code

• A statement that assigns a value to a variable

• A statement that ends a program

• A statement that defines a function

What is the purpose of initializing variables?

• To set their initial values

• To define a function

• To end a program

• To start a loop

What is the purpose of an if-statement in programming?

• To end a program

• To execute code conditionally

• To define a variable

• To repeat a block of code

What is a conditional statement?

• A statement that defines a variable

• A statement that initializes a loop

• A statement that runs based on a condition

• A statement that always runs

What is a while loop used for?

• To initialize variables

• To define a function

• To execute code while a condition is true

• To execute code a fixed number of times

What is the main difference between a while loop and a for loop?

• For loops are count-controlled

• While loops are count-controlled

• For loops are condition-controlled

• While loops are faster

Why are functions important in programming?

• They increase the complexity of code

• They allow for code reuse and abstraction

• They make code run faster

• They are only used for mathematical operations
