This page answers questions like these:

• What’s the difference between   char* s = "string";   and   char s[] = "string";   in C/C++?
  
• What’s the difference between   char* s;   and   char s[];   in C/C++?
  

Difference Between   char* s = "string";   and   char s[] = "string";

• Create a character pointer s which points to a section of memory containing the string string (including a terminating zero).
• You can change the value of s.  i.e. You can make it point to something else.
• sizeof(s) == sizeof(char*).

• Create an array s of 7 characters which contains the string string (including a terminating zero).
• You can’t change the value of s.  i.e. You can’t make it point to something else.
• This is similar to “const char* const s = "string";”.
• sizeof(s) == 7   because there are 7 characters in the string string (including the terminating zero).
