Rust Programming 2023 - A Comprehensive Course for Beginners - While Loop in Rust

The video tutorial explains the concept of indefinite loops, focusing on while loops where the number of iterations is unknown. It covers the use of the 'while' keyword, variable instantiation, and the logic behind incrementing a variable within a loop. The tutorial demonstrates how to print values during loop execution and clarifies the conditions under which the loop stops. It also discusses how to modify the loop condition to include or exclude certain values.

What is the primary use of an indefinite loop?

• To iterate when the number of iterations is unknown

• To iterate a known number of times

• To iterate over a fixed list

• To iterate in reverse order

Which keyword is used to declare a mutable variable in a while loop?

• let

• const

• mutt

• var

What is the initial value of the variable 'B' in the given example?

• 10

• 0

• 5

• 1

What happens when the condition 'B < 5' is used in the loop?

• The loop stops when B is 4

• The loop never starts

• The loop stops when B is 5

• The loop runs indefinitely

How can you modify the loop to include the value 6 in the output?

• Change the condition to 'B < 6'

• Change the condition to 'B > 5'

• Change the condition to 'B <= 5'

• Change the condition to 'B = 6'
