Use strncat

char *strncat(char * restrict s1,const char * restrict s2, size_t n);

The strncat function appends not more than n characters (a null character and characters that follow it are not appended) from the array pointed to by s2 to the end of the string pointed to by s1. The initial character of s2 overwrites the null character at the end of s1. A terminating null character is always appended to the result.Thus, the maximum number of characters that can end up in the array pointed to by s1 is strlen(s1)+n+1. If copying takes place between objects that overlap, the behavior is undefined.

thank you very jamoot, it works, and ticth, i don't want to learn lua right now because im only 13 and might be a video game designer so it might help if i know the basics of C.
EDIT::How would I clear a string??

It would help if you show us a little bit of code, so people can see exactly what it is your doing.
