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

The video tutorial guides viewers through creating a Solidity contract, focusing on initializing variables and creating a function called 'finalize'. It covers debugging and correcting logic errors, particularly in shorthand assignments. The tutorial concludes with a bonus question on conditional logic using if statements, emphasizing the importance of operators in Solidity.

What is the initial value assigned to variable A in the contract setup?

• 12

• 47

• 300

• 100

What type of function is 'finalize' described as?

• Private and viewable

• External and pure

• Public and viewable

• Internal and payable

What is the initial value assigned to the local variable D?

• 300

• 12

• 47

• 23

What is the correct shorthand assignment to multiply D by itself?

• D *= D

• D = D * D

• D += D

• D -= D

What was the incorrect result obtained when the function was first deployed?

• 300

• 47

• 253

• 517

What is the correct result after fixing the shorthand logic?

• 517

• 300

• 47

• 253

What condition is checked in the if statement for the bonus question?

• A > F and B < A

• A < B and B > F

• A > B and B < F

• A = B and B = F

What value is returned if the condition in the if statement is false?

• 23

• 47

• 12

• 0

What happens if B is made greater than A in the conditional logic?

• The function returns 0

• The function returns 23

• The function returns 253

• The function returns 517

What is the purpose of using an else statement in the function?

• To initialize variables

• To multiply D by B

• To return a default value

• To compile the contract
