    char path[1024];
    char fname[1024];
    char* location;
    FILE* files;
    int c;
    cout<<"your path file: "; cin>>path;
    cout<<"your file name: "; cin>>fname;
    location=strcat(path,fname);
   
   
   
    files=fopen(location, "w");
    if(!files)
    {
        cout<<"cannot opened files..\n";
        
    }
    else 
    {
        while(getchar()!=EOF){
            
           gets(teks);
           fputs(teks, files);
           fputs("\n", files);
        }
        
    }

    fclose(files);
    cout<<"   file created..."<<endl<<endl;
}


OK. when this execute. this program work correctly (i think). but, when I look the text file the firs char is deleted.
for example:
I input

hello...
learning cpp is great experience
so you must try it


then when I opened the text file, it will become

hello...
earning cpp is great experience
o you must try it


i'm really confused...
please help me..

getchar() reads one char.

That means that getchar() removes the first character and gets() gets the rest. So the first character is gone (like observed)

fputc(c, files);
c is always '\n'. Because of: c=getchar(). If you press return, it will print a newline to the file. Eventually:
1
2
3
4
5
6
7
8
 
c = 0;
do {
    gets(teks);
    if(c)
        fputc(c, files);
    fputs(teks, files);
    fputs("\n");
} while((c = getchar()) != EOF);

Or simply comment out the "fputc" line.

i try and out put is same before.
fputs("\n");
error

i try for change fputs become fputs("\n", files);
the output still same

Wait. gets attaches a \n character by itself. You can comment the fputs("\n",files) line.
EDIT: Or was it the getline? Check the References Section eventually.
