read files to unsigned int

How to store a file to unsigned int

  //Main.cpp

#include <iostream>
#include <fstream>

using namespace std;

unsigned int key[4];

int main(){
    ifstream file("key.txt");
    store(file);
    return 0;
}

i having this data in my key.txt

0xFDA5
0xD54E
0xFC00
0xB55A

I Created this function

void store(ifstream &file){
    int i = 0;
    if(!file)
        cout << "Couldn't open file " << endl;

    while(!file.eof()){

         file >> key[i];
         i++;
    }
}

it just looping nonstop. what should i change in order to store correct data to

key

The values you are reading in aren't unsigned integers. Use a hex modifier to convert when you pass in:

ex. file >> hex >> key[i];

so if want to output back the data with

0xFDA5
0xD54E
0xFC00
0xB55A

because when i output the data what i get is all numbers
when output should i covert to decimal or binary?
