using namespace std;
#include<fstream>
#include<iostream>

int main(){
ifstream fin;
ofstream fout;
int a=235,b=237;
fout.open("temp.txt");
fout<<a<<endl;
fout<<b<<endl;
fout.close();
fin.open("temp.txt");
int temp;
while(fin.eof()!=1){
    fin>>temp;
    cout << temp;
}
fin.close();
return 0;

output should be:235237
but instead of this ,,it is showing :235237237
hence,it is showing 237 2 times.
