pls send the answers for files,basic interview qustns,pointers and union to chandrakanthr09@gmail.com

1'st question answer is so simple just think of it once. .

logic is: a+~b+1;

#include
main()
{
int a,b;
printf("enter the values of a and b\n");
scanf("%d %d",&a,&b);
printf("%d",a+~b+1);
}

2'nd question is so what complex which cannot be understand by seeeing code

Program to reverse a Double linked list is

Steps to be Followed

1.Intially Get the first and last node address and keep with you as Head address and Tail address.
2.Each node in Double linked list contians Two pointer links i.e Front and back links
SWAP front and back links in each node of list.
3.And Finally Swap the HEAD nad TAIL address the the List is reversed. .

Answers for FILEs

1.Basically File is a collection of data or records used to store permantly.
FILE is a type defined structure present in STDIO.H

for clear understanding


typedef struct
{
short level ;
short token ;
short bsize ;
char fd ;
unsigned flags ;
unsigned char hold ;
unsigned char *buffer ;
unsigned char * curp ;
unsigned istemp;
}FILE ;

Here FILE is a new user defined data type whose members are shown above
So basially FILE is a structure

2. FILE pointer is basically a structure pointer which indirectly points to a structure which holds the FILE stream

4.SIZE of FILE type changes from operating system to operating system

for example in LINUX :sizeof(FILE)=148;
in Windows :Sizeof(FILE)=16;

No we cannot increment the file pointer,
if we do so the entire stream holded by structure pointer is will be lost.

SO never try to increment the File pointer
