What is "far" and "near" pointers in "c"...?

Answer / narasimha
"near" and "far" pointers are actually non-standard
qualifiers that you'll find only on x86 systems. They
reflect the odd segmentation architecture of Intel
processors. In short, a near pointer is an offset only,
which refers to an address in a known segment. A far pointer
is a compound value, containing both a segment number and an
offset into that segment.
Segmentation still exists on Intel processors, but it is not
used in any of the mainstream 32-bit operating systems
developed for them, so you'll generally only find the "near"
and "far" keywords in source code developed for Windows 3.x,
MS-DOS, Xenix/80286, etc.

I think it's kind of pointer for different computer
architecture such as X86, IBM power server and so on because
various model of memory model is different.

Is the following code legal? typedef struct a { int x; aType *b; }aType
In the following pgm add a stmt in the function fun such that the address of 'a' gets stored in 'j'. main(){ int * j; void fun(int **); fun(&j); } void fun(int **k) { int a =0; /* add a stmt here*/ }
main() { char a[4]="HELL"; printf("%s",a); }
main() { int i=-1,j=-1,k=0,l=2,m; m=i++&&j++&&k++||l++; printf("%d %d %d %d %d",i,j,k,l,m); }
int aaa() {printf(“Hi”);} int bbb(){printf(“hello”);} iny ccc(){printf(“bye”);} main() { int ( * ptr[3]) (); ptr[0] = aaa; ptr[1] = bbb; ptr[2] =ccc; ptr[2](); }
void main() { int const * p=5; printf("%d",++(*p)); }

create a C-code that will display the total fare of a passenger of a taxi if the driver press enter,the timer will stop. Every 10 counts is 2 pesos. Initial value is 25.00
main() { register int a=2; printf("Address of a = %d",&a); printf("Value of a = %d",a); }
