The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Exercise - Final Solidity Operator

The video tutorial guides students through a final operators exercise, where they are tasked with creating a contract called 'final exercise'. The contract involves initializing three state variables (A, B, and F) with specific values. Students then create a public and viewable function called 'finalize' that returns a local variable D, initialized to 23. The function includes a conditional logic to return a modified value of D based on the comparison of A, B, and F. The tutorial encourages students to attempt the exercise independently before reviewing the solution together.

What are the initial values assigned to the state variables A, B, and F?

• A = 250, B = 10, F = 40

• A = 200, B = 15, F = 45

• A = 100, B = 20, F = 50

• A = 300, B = 12, F = 47

What is the initial value of the local variable D in the 'finalize' function?

• 10

• 23

• 30

• 50

Which operation is performed on D before it is returned in the 'finalize' function?

• D is divided by B and then added to B

• D is multiplied by B and then subtracted by B

• D is added to B and then multiplied by B

• D is subtracted by B and then divided by B

Under what condition will the 'finalize' function return the multiplication result?

• If A is equal to B and B is equal to F

• If A is greater than or equal to B and B is less than F

• If A is less than B and B is greater than F

• If A is less than B and B is less than F

What should the 'finalize' function return if the condition is not met?

• The sum of A and B

• The initial value of D, which is 23

• The value of F

• The value of B
