//A NICE LOGIC TO GET MAX.SIZE OF POINTER U CAN GET..IN 4 GB RAM..//

//I GOT 32MB ...OF MAX. FOR POINTER AFTER THAT ..I GOT SEGMENTATION FAULT..//

#include<stdio.h>

#include<stdlib.h>

int main()

{

unsigned long long int* ptr;

ptr=malloc(100000000000000);//if while mallocing all the memory is allocated ...then on starting of run time ..segmentation fault is come ..//but it does not segmentation fault came after putting number of values into ptr..//means memory to pointer is provided while putting values as required..//

int i=0;

for(i=0;i<10000000000;i++)//as i operated no. of times..//

{

ptr[i]=i;//value is being putted into pointer..//

printf("%lu\n",*(ptr+i));
