Please debug this program

[TheDeveloper]

main()
{
printf("%d",i);
sum();
printf("%d",i);
}

static int i;

sum(void);
{
++i;
}

Please tell me if this program runs or not
If error occurs, what should be the error and the reason ?

thanks

The program compiles and runs without any error.

Are you sure you can trust me? Read the homework policy and use your compiler to find out if I told you the truth.

You mean errorS?

If this is all code there is, then it may compile, but should not necessarily do so.
You suffer firstly from "default int". All functions should return something. Not nothing.
Secondly, since the definition of sum appears below main, it should have a prototype (every function should have one, really).
Thirdly, there is a stray ; after the function definition of sum.

It certainly won't since i was not declared before the first two points where it is used.

[mMarko]

Also "i" isn't declared and there is no value assigned to it. Plus even if you do all that the program probably won't do what you liked it to do...

edit: damn I'm slow

[Elysia]

Sure, i is declared. On global level, which means it will be initialized to 0, as well.

[mMarko]

static int i;

Oh yes, I wasn't looking for the declaration of a variable used in main, on the lines after it's used

Ok then, since it's global the second part of my post doesn't apply too

...but it should be before main anyway

[cpjust]

Including a certain header file would help too.

Er, no.
Get a compiler, and use it.
