42. The following 'C' program main { unsigned int num; int i; scanf("%u",&num); for(i=0;i<16;i++) printf("%d",(num<<i&1<<15)?1:0); }
Prints all even bits from num
Error
Prints binary equivalent of num
none of these
43. Output of the following 'C' program is main { printf("\n%x",-1>>4); }
ffff
0fff
0000
44. The following 'c' program main() { unsigned int m[]={0.01,0.02,0.04,0.08,0.10,0.20,0.40,0.80}; unsigned char n,i; scanf("%d",&n); for(i=0;i<=7;i++) if(n&m[i]) printf("\nyes"); }
Putting of all bits which are on in the number n
Testing whether the individual bits of n are on or off
Would give an error
Undefined
45. In a 'C' program, constant is defined
Before main
After main
Anywhere, but starting on a new line
Anywhere in the program
