Q2.

What is printed by the following ANSI C program? #include < stdio.h > int main(int argc, char *argv[]) { int x = 1, z[2] = {10, 11}; int *p=NULL; p=&x *p=10; p =&z[1]; *(&z[0]+1)+=3; printf("%d, %d, %d \n",x,z[0],z[1]); return 0; }

Q3.

Following declaration of an array of struct, assumes size of byte, short, int and long are 1,2,3 and 4 respectively. Alignment rule stipulates that n byte field must be located at an address divisible by n, the fields in the struct are not rearranged, padding is used to ensure alignment. All elements of array should be of same size. Struct complx Short s Byte b Long l Int i End Complx Complx C[10]Assuming C is located at an address divisble by 8, what is the total size of C, in bytes?
