@Hubiab – I don’t know exactly what you mean, because this C language tutorial is about removing files.
So I make the assumption that you mean without any code around the remove() function. I get this on windows:

#include
void main()
{
remove(“c:/test.txt”);
}

Hope that this is what you mean.

My fault, I see now what the problem is: ‘gets_s’ is not part of the C standard, so it depends on your compiler if it is implemented. I use visual studio and they have implemented ‘gets_s’ and it looks like your compiler doesn’t.

I don't know exact what the problem is (looks your missing an include), but I re-tested the two examples again using VS 2008 (console application) and they worked fine. To get your source code example to work I had to add #include (for the system(); function), then it also works. More info about gets_s and why to use it can be found here

I got this to work!

#include

int main(void)
{
char filename[101], newfilename[101];

printf (“Please type in name of file to be changed:\n”);
scanf(“%s”, &filename); /* Get the filename from the keyboard) */

printf(“You have choosen to rename %s.\nPlease type the new name of the file:\n”, filename);
scanf(“%s”, &newfilename); /* Get the new filename from the keyboard) */

if(rename(filename, newfilename) == 0)
{
printf(“%s has been rename %s.\n”, filename, newfilename);
}
else
{
fprintf(stderr, “Error renaming %s.\n”, filename);
}
system (“pause”);
system (“CLS”);

return 0;
}

This example does not work! Using Dev C++ compliler version 4.9.9.2 as well I receive the following compile error:
[Linker error] undefined reference to `gets_s’
