How can I save the data into a file and save it on the hard disk?

sevenbox

I got an array Error containing 20 data in the xxDoc class. I want to save the data to a specified folder in the format of a text file. How can I write the code? What about saving as an Excle file?

mystonelh

#include <fstream.h>

writedata.open ("[file name]", ios :: out);
if (! writedata)
    MessageBox ("Error while saving file", "Error", MB_OK);
else
{
   writedata << variable 1 << variable 1 .... << variable 20;
   writedata << "\n";
   writedata.close ();
}
CFile class is also available

Weakly ask what kind of instance is writedata?

Use the CFile class, just write a log file
Very simple
You want me to give you a class
The ones written in the Excle file can be found on the Internet, and those that have been found before, please go and see for yourself
