Question

Write the output of the following cout statements, showing the steps of your work.
auto value_1 = -1, value_2 = -4, value_3 = 9;
if (value_1 == value_2 || value_3 / 3 > value_2)
{
if (value_1 - 2 * value_2 == 1)

cout << "A";
else if (value_3 * -1 > 0)

cout << "B";
} else {
cout << "C"; }

Answer 1

Answer:

This will code print nothing, as it may show the "Program finished with exit code 0 " on the console window.

Explanation:

We will run code line by line.

Given values, auto value_1 = -1, value_2 = -4, value_3 = 9;

if (value_1 == value_2 || value_3 / 3 > value_2) that is (-1 == -4 || 9/3 > -4) condition is true as 3>-4 will move into if.

now check inner if statement

if (value_1 - 2 * value_2 == 1) i.e. (-1 -2 * -4 == 1 ) which is false as (7 !=1)

so will move to else if condition.

else if (value_3 * -1 > 0) i.e. (9 * -1 > 0) which is false as -8 is not greater than 0

As we can see that there is no else statement, so it would print nothing and program will exit with code 0.

Note: It would not also print C as outer if condition is true, so will not go to else.
