difference between char *s and char s[ ]

标签：

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.
