4.
What will be the output of the program (in Turbo C under DOS)?
#include<stdio.h>
int main()
{
char huge *near *far *ptr1;
char near *far *huge *ptr2;
char far *huge *near *ptr3;
printf("%d, %d, %d\n", sizeof(ptr1), sizeof(ptr2), sizeof(ptr3));
return 0;
}

Don't understand the concept of near far huge pointers. Help me by explaining this.

Irrespective of pointer it declares far is of size 4,
Huge is of size 4,
Near is of size 2.
Huge is of size 4,
Near is of size 2.

Why we consider the size of far, huge and near as 4, 4 and 2 respectively. Then in declaration of first line also there is near so why it takes 4bytes of size?

What is the purpose of near, huge and far pointers. Explain with an example program?

Actually far and near are related to fact that how we are accessing the variable i.e. absolute or relative.
Relative = "near";.
Absolute="far".
When we are accessing variable relative, then we hav to store only relative address that account for our 2 bytes of memory.
And the rest is understood.
Relative = "near";.
