Select the correct answer.
a. This program writes “1” to the standard output.
b. This program writes “7” to the standard output.
c. This program writes “8” to the standard output.
d. This program writes “4” to the standard output.
e. This program writes “0” to the standard output.
Answer explanation
- The first condition if(y++ == 4) returns true, because y is incrimented by one after the evaluation.
- The statement x += 4; increments the value of x by 4, so x = 1 + 4 = 5.
- The value of y is now equal to 5.
- The condition if(y == x) returns true. So, x += 2; increments the value of x by 2, x = 5 + 2 = 7.
- The condition if(x > y) returns true, because x is greater than y. So, the statement x++; increments the value of x by one, x = 7 + 1 = 8.
The correct answer is: c.
