Consider a system with byte-addressable memory, 32-bit logical addresses, 4 kilobyte page size and page table entries of 4 bytes each. The size of the page table in the system in megabytes is ________.

What is the output of the following C code? Assume that the address of x is 2000 (in decimal) and an integer requires four bytes of memory.

int main () { 
unsigned int x[4][3] = 
          {{1,2,3},{4,5,6},{7,8,9},{10,11,12}}; 
          printf(“%u, %u, %u”, x+3, *(x+3), *(x+2)+3); 
}

Consider the following pseudo code, where x and y are positive integers.

begin 
    q := 0 
    r := x 
   while r ≥ y do 
      begin 
      r := r - y 
      q := q + 1 
    end 
end

The post condition that needs to be satisfied after the program terminates is

The output of the following C program is__________.

void f1(int a, int b) { 
int c; 
c=a; a=b; b=c; 
}

void f2(int *a, int *b) { 
int c; 
c=*a; *a=*b; *b=c; 
}

int main(){ 
int a=4, b=5, c=6; 
f1(a,b); 
f2(&b, &c); 
printf(“%d”,c-a-b); 
}
