拜託!

如何讀一個txt然後將它存到另一個txt
for example:

/* Program to create backup of the AUTOEXEC.BAT file */
#include
int main(void)
{
FILE *in, *out;
if ((in = fopen("\\AUTOEXEC.BAT", "rt"))
== NULL)
{
fprintf(stderr, "Cannot open input file.\n");
return 1;
}
if ((out = fopen("\\AUTOEXEC.BAK", "wt"))
== NULL)
{
fprintf(stderr, "Cannot open output file.\n");
return 1;
}
while (!feof(in))
fputc(fgetc(in), out);
fclose(in);
fclose(out);
return 0;
}

------
What do we live for if not to make life less difficult for each other?

如果內容一樣!!
可以考慮直接檔案復制!!

CopyFile

The CopyFile function copies an existing file to a new file.
BOOL CopyFile(
LPCTSTR lpExistingFileName, // pointer to name of an existing file
LPCTSTR lpNewFileName, // pointer to filename to copy to
BOOL bFailIfExists // flag for operation if file exists
);
