The difference here is that :
char *s = "hello,world!";
will place hello,world in read-only part of the memmory and makes s a pointer to that. making any writing operation on this illigal.
while:
char s[] = "hello,world!";
will puts the hello,world in read-only memmory and copies the string to newly allocated memmory thus making :
s[0] = ‘j‘;
legal.
