Why i am getting error?

Question

int t=20;
(t<18) ? t++ : t-- ;
cout << t;

It gives me error but why?

Answer 1

It may be that an invisible character is making a blome.

If you want you can compile it in sololearn or in tio.run. Both are good for this.

I also recommend reporting the error in W3CSchool.

Answer 2

¿ERROR?. When you compile and run it, it is quality. What error message does it give you?

Answer 9

Have you copied this code from anywhere

Answer 10

You have to use conditional statements along with correct operators

For example:

int t = 20;
if (t<18) {
t++;
}
else {
t--;
}
