Basic Single Line Function

I am trying to create a simple(supposedly) single line function named f2 that takes one int argument named x, and returns a double value equal to 1.0/x but doesn't print anything. I am getting error after error, and I am not sure what the protocols are for creating and separating different parts of a function on one line or if I can even do this. Here is what I have: 

f2(int x) { scanf("%i", &x); int c = (1.0/x) return x}

I am trying to use ch to see if it runs and I am not sure if that could, possibly, also be the problem.

Your code doesn't do any part of what you specify...

There is no reason to use scanf. You also use an int to store a floating point value. You also don't return the calculated value.

Here is your function, expanded for clarity:

double f2(int x){
    double val = 1.0 / x;
    return val;
}

One line:

double f2(int x){ return 1.0 / x; }
