Segmentation fault in a function

I want to find the address of an integer in an array. Debugger revealed that line 8 is at fault. if (*i==item) {ans=i;};

Variable ans is local and not null, yet segmentation fault occurs. Why is that and how can I fix it?

#include <stdio.h>

int* finder(int *begin, int *end, int item)
{
    int *ans=0; int *i=begin;

    while (i<end) {
        if (*i==item) {ans=i;};
        i++;
    }

    return ans;
}

int main()
{
    int arSize, target, i=0;
    int arr[10]={};
    int *first=&arr[0]; int *last; int *result;

    printf("Find element: ");
    scanf("&d",&target);
    printf("Array size: ");
    scanf("&d",&arSize);
    printf("Enter array: ");
    while (i<arSize){
        scanf("&d",&arr[i]);
        i++;
    }

    last=&arr[arSize];
    result=finder(first,last,target);

    printf("%s %p","Target's address is ",result);


    return 0;
}
