12. 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.
13. Now some questions about extern variables.#include<stdio.h>main() { 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 same.in the question paper, the original word is "hello".
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.

3. 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.
