Question:

what is static import in java?

Vikas S.
Answer:

In java whenever we have to use methods or variables of another class we usually import that class and then use its functions and variables. for example: import java.lang.Math; //inside class double test = Math.PI * 5; Instead of importing the whole class we can just import methods or/and variables of that class by using the static import. Example: import static java.lang.Math.PI; //no need to refer class now double test = PI * 5;

Question:

what will be the output of the following program 1 #include "stdio.h" 2 int main() 3 { 4 void *pVoid; 5 pVoid = (void*)0; 6 printf("%lu",sizeof(pVoid)); 7 return 0; 8 }

Vikas S.
Answer:

At line number 4 we are creating a void pointer(a pointer that can point to any data type) now on line 5, 0 is assigned to that pinter. so this is the address that pvoid will hold now. As a pointer just hold an integer which should be a valid memory address, otherwise it can through an error at runtime. In the next line, we are printing size of this pointer so size will be equal to the size of int
