fstreamで配列を保存する

#include <fstream>
using namespace std;


int data[5] = {10,20,30,40,50};

ofstream ofs("test.data",ios_base::binary | ios_base::out);
ofs.write((const char*)data, sizeof(int)*5);


int data2[5];
ifstream ifs("test.data",ios_base::binary | ios_base::in);
ifs.read((char*)data2, sizeof(int)*5);
