What is the output of the following code if int x = 5;?

• • Equal to 10

• • Not equal to 10

• • No output

• • Compilation error

Answer explanation

The condition mistakenly uses = for assignment instead of == for comparison, so x = 10 makes x equal to 10, which is non-zero (true), and the if block executes.

What will the following code print if int grade = 75;?

• • Excellent Done

• • Good Done

Answer explanation

grade is 75, so grade > 70 is true, which makes "Good" print. The final cout << " Done"; is outside the conditions, so "Done" is also printed.
