Question

C++ Question: what is in the blanks?

code:
int x = 24;
int y;
y = _-12;
cout<<_<<endl;

Answer 1

You didn't specify what the program should output, so there are many possibilities that result in a working program. It *looks* like this was intended:

int x = 24;

int y;

y = x-12;

cout<<y<<endl;

and it will display 12.
