2.----means allowing objects of difference types to be considered as examples of a higher level set :
ans: Generalization

3.The primary characteristic of key field is that it must be unique

4. Manager-------------- --emp managed by ans:one of many recursive relationship

a) static fn
b) non static fn
c) default constructor
d) none

6.class constest
const int i;

struct abc
int i;
abc(int j)
{ i=j;}
void display()
{ cout< class sample { public : sample(int **pp) { p=pp;} int **p; int **sample:: *ptr=&sample ::p;

11. In a file A...Z characters are written.if we open the file using fopen and
what will be the output.?
Ans . Y.(please verify Here last parameter is the integer value to seel_end

12.Same question with
ans. 11th character will be printed "K" verify.

13.Theory question about far pointers.

Hint: Far pointers are 4 bytes in size and local pointers are 2 bytes in size. important: i saw in a previous question paper of accenture which is in the chetana database, some lady wrote that size of an integer in C is 2 bytes and for C++ it is 4 bytes. This is absurd.The size of types is entirely dependent on the compiler used.for DOS Turbo C sizeof int is 2 and float is 4 bytes for windows borland C,C++ size of int is 4 bytes for linux gcc, size of int is 2 bytes. All these depends on the Operating system.Please keep this in mind.

char str[]={"hell"};
int i;
for(i=0;i<5;i++) printf("%c%c%c%c\n",str[i],i[str],*(str+i),*(i+str)); getch(); }
ans. hhhh eeee llll llll note that str[i] and i[str] are the the question paper, the original word is "hello".

15.Which of the following is not defined in string.h strtod,memchr,strspn,strchr
ans . strtod.(defined in STDLIB.H) it is used to convert a string to double.

16.Questions on macros with arguments .same pattern given in TEST UR C SKILLS
eg.#define SQUARE(x) x*x
ans. when the macro expands we get 2+3*2+3 = 2+6+3 =11.11 is the correct answer not 25.
Remember an inline function does type checking and so it is better than a macro a question on this.

17.Some memory is allocated using memalloc and then realloc is called. and now to write the size of the variable.better learn memalloc and realloc. what it does and syntax.
