What will be the output of the program ?

  #include<stdio.h>
  int main()
 {
     int x=30, *y, *z;
     y=&x; /* Assume address of x is 500 and integer is 4 byte size */
     z=y;
     *y++=*z++;
     x++;
     printf("x=%d, y=%d, z=%d\n", x, y, z);
     return 0;
 }

2) Can you combine the following two statements into one?

   char *p; 
   p = (char*) malloc(100);

3) A pointer is

4) Which of the following does not initialize ptr to null (assuming variable declaration of a as int a=0;)?

5) What will be the output of the program If the integer is 4bytes long?

 #include<stdio.h>
 int main()
 {
     int ***r, **q, *p, i=8;
     p = &i;
     q = &p;
     r = &q;
     printf("%d, %d, %d\n", *p, **q, ***r);
     return 0;
 }
