💡 Hint

Common Mistakes

Using String instead of an integer type.

Using bool which is for true/false values.

Using f64 which is for floating-point numbers.

The i32 type is the default integer type in Rust for 32-bit signed integers.

Common Mistakes

Using i32 which is for integers.

Using bool which is for true/false values.

Using char which is for single characters.

The f64 type is the default floating-point type in Rust for 64-bit floats.

💡 Hint

Common Mistakes

Using integer or floating types for boolean values.

Using char which is for characters.

The bool type is used for true or false values in Rust.

4fill in blank

hard

Fill both blanks to declare a character variable letter with value 'A'.

Rust

let letter: [1] = [2];

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using double quotes which create a string, not a char.

Using String type for a single character.

The char type stores a single character, which is written with single quotes like 'A'.

5fill in blank

hard

Fill all three blanks to declare a tuple data with an integer, a float, and a boolean.

Rust

let data: ([1], [2], [3]) = (42, 3.14, true);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up types or using char incorrectly.

Using string types instead of scalar types.

The tuple contains an integer (i32), a floating-point number (f64), and a boolean (bool).
