problem with strcpy() and arrays

[GregV1]

I am using Borland Builder 5. I have a problem with variables. I have a char array of length nine. I only use characters '0' '1' and '2'.
When I use strcpy() sometimes it puts a '\' character somewhere in the string. Also when I dont use stringcopy it still does the same thing (altering the values of the array).
How is this possible?

Thank you.

Which project do you use in C++Builder. Console? Are you writing C? Maybe the '\' comes from the null terminating Character '\0'. It is the reason why you should declare a character array one character longer than the largest string that it is to hold.
And a for loop will look like:
for(int i=0; string !='\0'; i++)

Be aware between the difference of 'a' and "a".
when you use strcpy(s1,"a") instead of strcpy(s1,'a') a null char '\0' will added.
