small doubt in filehandling
 

hello everyone
please help me with the following code:
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
fstream fin;
fin.open("data", ios:: out);
string str;
cin >> str;
fin << str;
fin.close();
fin.open("data", ios::in);
while(fin) {
fin.get(ch);
cout << ch;
}
return 0;
}

if the input is : priya
the output should be priya
but my code is showing the output as priyaa
please help me to sort out the problem with the above code

Perhaps you mean this:

ohh thank you so much . Now its working properly. But will you please say me what is the difference. And also have a look at this code

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
fstream fin, fin1;
fin.open("copy", ios :: out );

int n;
string str;
cout << "enter no of lines" << endl;
cin >> n;
int i = 0;

do {
getline( cin, str );
fin << str << endl;
i++;
}

while ( i < n );

fin.close();
return 0;
}
In this code i am entering 5 lines but it is taking only 4 lines as input. can u please help me in this case also.what is my wrong here??

I'm not sure why that happens but as a workaround, you could flush input with ignore() before reading again:

thank you so much. My doubt is cleared.
