Predict the output or error(s) for the following?

main()
{
int *j;
{
int i=10;
j=&i;
}
printf("%d",*j);
}

A.	8	B.	0
C.	9	D.	10

Answer and Explanation

Answer:10

Explanation:
The variable i is a block level variable and the visibility is inside that block only. But the lifetime of i is lifetime of the function so it lives upto the exit of main function. Since the i is still allocated space, *j prints the value stored in i since j points i.
