Code:
int str_join(char *a, const char *b) {
int sz =0;
while(*a++) sz++;
char *st = a -1, c;
*st = (char) 32;
while((c = *b++)) *++st = c;
*++st = 0;
return sz;
}
....
char a[] = "StringA";
printf("string-1 length = %d, String a = %s\n", str_join(&a[0],"StringB"), a);
Output:
string-1 length = 7, char *a = StringA StringB

I don’t understand why it’s showing stack smashing? and what is *stack smashing? Or is it my compiler’s error?
