Steering the control

[saurabhamiable]

Can anyone please tell me that how the control flows in the following code and what will be its output?

main()
{
int fun(int);
int i=3;
fun(i=fun(fun(i)));
printf("%d",i);
}
fun(int)
{
i++;
return(i);
}

Did you try putting this into a compiler?

return(i);
}

There will be no output at all.Compile errors.

Fist when defining the function ISO forbids defining it without return type,second if you want to increase i inside the function you will have to declare function like:
int fun(int i);
