Question
Help -
void main ()
{
int a=-5;
-a;
cout<<a;
... }
Output is -5
Why isnt dis output 5 ..

Answer
Hello Vikas.

The line:
-a;
does evaluate the negative of "a", but the result is not stored. To change the value of "a", the result has to be assigned back to "a".

If you change the line to:
a = -a;

You will get the result you expect.

I hope that answers your question.

Best regards
