4. What is the output of the following C Program?

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

Answer: Option B

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.
