I tried the following:

#include<stdio.h>
#include<math.h>
#include<string.h>

int main (){

    unsigned long long int *inputNumber;
    int i = -1;
    int memoryUsed = 0; //256 KB limit

    unsigned long long int input= 0;

    while( input != EOF ){
           scanf("%llu", &input);
            if( input == EOF)
                break;
                if ( memoryUsed > 262144 ){
                    printf("memory Exceed");
                        break;
                }
            inputNumber[++i] = input;
            memoryUsed = memoryUsed + 8;
    };

    for(  ; i >= 0 ; i-- ){
        printf("%.4f\n", sqrt(inputNumber[i]));
    }

    return 0;
}

but it gives same error
