if I input 1 or 2, the compiler prints the result four times, I think the problem is on the main function.

Answer 1

When you input 1 or 2 , you are calling this ChoseOne1(Num); function 4 times.. actually no use. You can remove line 20 and else part. Which does nothing..

edit: Zakarya Meddahi
just use like :

if(strcmp(ChoseOne1(Num), "\0") != 0)
{
strcpy(string, ChoseOne1(Num));
printf("%s\n", string);
}

instead of

strcpy(string, ChoseOne1(Num));
if(strcmp(ChoseOne1(Num), "\0") != 0)
{
printf("%s\n", string);
}
else if(strcmp(ChoseOne1(Num), "\0") == 0)
{
ChoseOne1(Num);
}

hope it helps.

Put your code in the code playground, and share the link. That will make it easier to debug.
