What's wrong here?

Question

#include <stdio.h>
#include <string.h>

int main() {
char txt[200];
int L,i;
printf("veuillez taper un texte: \n");
gets(txt);
L=strlen(txt);
for(i=L-1;i>=0;i++)
{
printf("%c",txt[i]);

}

return 0;
}

Answer 1

Remove the first printf, it is not necessary to print texts that aren't required in challenges.

Since the program is iterating the char backwards, the incremention should be i-- and not i++.

Answer 2

And use fgets() instead of gets()
fgets(txt, 200, stdin);

Answer 3

Ty it works
