Answer 1

the code is working properly. but when you does not enter a value it choose some random value.

try int x=0;

or any default value.

Answer 2

They are printing next to each other, so when input is 8 printSomething prints 8 and then
cout << timesTwo(x) << endl; print 16 without first placing a newline, so you should change printSomething to this:

void printSomething(int x) {
cout << x << endl;
}

Answer 3
