(b) Explain what is the purpose of the code in the mystery block or, in other words, what is the value calculated in i2. #include #include Fint main() { unsigned int il, i2; unsigned int student_id = 12363458; // Put your student ID here int j, k; system("dir"); printf(" xx = %d ", (student_id % 255) & exfe); for (j=0; j>= 16; il += i2; il & Oxfffe; // il now contains a zero in bit o, and 'info' bits from bit 1 to // bit 15. 12 = 1/ Begin mystery block il; for (k=15; k>0; k--) i2 = 12 ^ (il >> k); i2 = i2 & 1; // End mystery block il = il | i2; printf("xXx ", il); return
