i=20;
cout<<sizeof(i);
}

The code outputs 8, which is the size (in bytes) of a double type variable i, why? the sizeof() returns that value (the double type variable i size) and cout stream the value to the screen.

Answer 2

Output is 8 because sizeof is a function that returns the size of a variable or a constant. The default size of double is 8 bytes
