Ans: 0 0 0 0
The first thing you have to remember is that static
variables are initialized only once. The second thing is
that static variables have a life time scope and they retain
their value between function calls.
"i" is first initialized to 5. in the if condition the value
of i is changed to 4. main() is called again and the value
of i is changed to 3 in the if condition and main is called
again. Now the value of i is changed to 2 and main is called
again. Now the value of i is changed to 1 and main is called
again. After this the value of i is changed to "0" and the
block is excited.
As the value of i is now "0", it is printed 4 times for each
of the calls for main(). So the ans will be
0

static variable's value is stored in memory statically upto
end of the program. so if the variable comes out of the
function it retains its value

This prog'll not produce any output since the value of i
reduces when it reaches zero if block will not be executed
and the program is terminated....
