Question

What will the following code display?

int number = 6
int x = 0;
x = --number;
cout << x << endl;




1. 7

2. 6

3. 5

4. 0

Answer 1

5

Step-by-step explanation:

The operator '--number', it is a pre decrement operator which decrement first and then assign. It decrement the value by 1.

initially the number is 6.

x is 0.

then, x = --number;

it decrement the number by 1 first and then assign to x.

so, x assign the value 5.

finally, print the value.

Therefore, the answer is 5.
