I have a loop in that i have data of three types and i want to asve it on
cvs file format. Saved data should be some thing like this

Just output a comma as the separator between each value. At the end of each line, instead of a comma, use an ordinary newline or endl.

Hi ,

i tested the below program.

#include <iostream>
#include <fstream>
#include<string>
#include <iomanip>
using namespace std;
int main()
{
	ifstream indata;
	ofstream outdata;
	outdata.open("aaron.csv", ios::app);
	outdata << "a1,b1,c1" << endl;
	outdata << "a2,b2,c2" << endl;

	indata.open("aaron.csv");
	string cell1;

	indata >> cell1;

	cout << cell1 << "\n\n";

	system("pause");
	return 0;
}

When i run the program every time. i found previously runned data with my newly saved data.
I want to update the saved data. don't want to maintain previous data. how can fix it . thanks

Well, you opened the file in append mode, with the ios::app option.
That's why it appends the new data to the end of the existing file.
