Write your own strcat() function.

Here is a C function which implements the strcat() function...


/* Function to concatenate string t to end of s; return s */
char *myStrcat(char *s, const char *t)
{
char *p = s;

if (s == NULL || t == NULL)
return s; /* we need not have to do anything */

while (*s)
s++;

while (*s++ = *t++)
;

return p;
}
