FTP

#include<iostream>
#include<windows.h>
#include<Wininet.h>

using namespace std;


int main()
{
    HINTERNET hInternet;
    HINTERNET hFtp;


    hInternet=InternetOpen(0,INTERNET_OPEN_TYPE_DIRECT,0,0,0);
    if(hInternet == NULL)
      cout<<"\n1)Something goes wrong...\n";
    else
      cout<<"\n1)Everything is perfect...\n";



    hFtp = InternetConnect(hInternet,"xxx.xxx.xxx",INTERNET_DEFAULT_FTP_PORT,"user","pass",INTERNET_SERVICE_FTP,0,0);
    if(hFtp == NULL)
      cout<<"\n2)Something goes wrong...\n";
     else
      cout<<"\n2)Everything is perfect...\n";


    char szFile[] = "log";
    strcat(szFile,".txt");

    FtpPutFile(hFtp,szFile,"file.txt",INTERNET_FLAG_TRANSFER_BINARY,0);



    InternetCloseHandle(hFtp);
    InternetCloseHandle(hInternet);

    return 0;

}

This is my source.It works perfect,and in my ftp file a file named "file.txt" is created from this code
FtpPutFile(hFtp,szFile,"file.txt",INTERNET_FLAG_TRANSFER_BINARY,0);

But i have two questions:
1)With this code

char szFile[] = "log";
    strcat(szFile,".txt");

It works,but if i change the char szFile[] = "log"; to char szFile[] = "something else"; It does not work.Why?

2)How i can put something into the file that is created?

Thanks...

We already were helping you in this thread?

1) What is "something else"? Why not just create it with the .txt already applied? It looks like a completely unnecessary function call. Anyways, I'm surprised the former works. That should cause a segmentation fault. Try creating an array that is actually big enough to hold what you're looking for, or use std::string.

2) Using file I/O. http://www.cplusplus.com/reference/cstdio/
