SECTION ?II (C language Basics and programming) this section consists of 20 Questions??.. All are programs only?
1. main()
{
printf(“%x”,-1<<4); } a) fff0 b) fffb c) ff0 d) none Ans: a Explanation: -1 is internally represented as all 1’s. When left shifted four times the least significant 4 bits are filled with 0’s.The %x format specifier specifies that the integer value be printed as a hexadecimal value. 2. main() { char *p; p=”Hello”; printf(“%cn”,*&*p); } a) e b) H c) some address d) ome garbage value Ans: b Explanation: * is a dereference operator & is a reference operator. They can be applied any number of times provided it is meaningful. Here p points to the first character in the string “Hello”. *p dereferences it and so its value is H. Again & references it to an address and * dereferences it to the value H. 3. void main() { int i=5; printf(“%d”,i++ + ++i); } a) 11 b) 12 c) 10 d) output cant be predicted Ans: d Explanation: Side effects are involved in the evaluation of i 4. main( ) { int a[2][3][2] = {{{2,4},{7,8},{3,4}},{{2,2},{2,3},{3,4}}}; printf(?%u %u %u %d n?,a+1,*a+1,**a+1,***a+1); } a) 100, 100, 100, 2 b) 101,101,101,2 c) 114,104,102,3 d) none Ans: c
