Relational operators in Rust - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are relational operators in Rust?

Relational operators compare two values and return a boolean (true or false) based on the comparison.

beginner

What does the operator < mean in Rust?

The < operator means "less than". It checks if the value on the left is smaller than the value on the right.

beginner

How do you check if two values are equal in Rust?

Use the == operator to check if two values are equal. It returns true if they are the same, false otherwise.

beginner

What is the difference between == and != operators?

== checks if two values are equal, while != checks if two values are not equal.

beginner

What will the expression 5 >= 3 return in Rust?

It will return true because 5 is greater than or equal to 3.

Which operator checks if a value is greater than another in Rust?

A !=

B <=

C >

D ==

The > operator checks if the left value is greater than the right value.

What does the expression 4 != 4 evaluate to?

A true

B false

C error

D 4

4 != 4 means '4 is not equal to 4', which is false.

Which operator would you use to check if two values are equal?

A ==

B <

C !=

D >=

The == operator checks if two values are equal.

What is the result of 7 < 10 in Rust?

A true

B 7

C false

D error

7 is less than 10, so the expression returns true.

Which operator means 'greater than or equal to'?

A <=

B !=

C ==

D >=

The >= operator means 'greater than or equal to'.

Explain what relational operators are and list the common ones in Rust.

Think about how you compare numbers or values in everyday life.

Describe how you would use relational operators to compare two numbers in Rust and what type of value the comparison returns.

Remember, comparisons answer yes/no questions.
