Thread: Write output of given program

Code:

int x=1234;
int y = func(x);


int func(int x)
{
	int j;
	if (x <10)
		return x;
	else {
		j = x%10 + func(x/10);
		printf("%d",j);
	}
}

it outputs the sum of digits

since there is no statement like return j; in the else part of func, hence 3 is printed first and then 2 random numbers after that...
if the else part is like :
else {
j = x%10 + func(x/10);
printf("%d",j);
return j;
}

then the ouptut is:
