What is the output?

[Plowman]

I want to double check myself, not 100% sure. Any help is appreciated, thanks in advance.

int g;
void afun(int x)
{
int y=0;
static int z=0;
x++; y++; z++; g++;
cout << x << ' ' << y << ' ' << z << ' ' << g << endl;
}
void main( )
{
int a=7;
afun(a);
g++;
afun(a);
cout << a << ' ' << g << endl;
}

Main should return an int but anyways why can't you compile it yourself? Or are you just not willing to compile it yourself? Or you could alternatively follow the code

Also keep in mind globals are 0 initaliEd and statics have a lifetime of globals but in this case local to a function

What is the output?

error: '::main' must return 'int'

After fixing that, here is expected output:

8 1 1 1
8 1 2 3
7 3

If you cannot compile it yourself, here is some sites:

Output of g is undefined. You don't initialize it.

Global variables are zero-initialized:
