First one mean "pointer to a constant" and second one is "constant pointer". In first case "content can't modify" while in second case myPointer can not point to another location.

Below Example Will Help You In Understanding The Difference:

1)const char *myptr
Ex:
char ch = 'a';
const char *myptr = &ch;
*myptr = 'b' <---- Not Possible
myptr++; <-----Possible

2)char *const myptr
Ex:
char ch = 'a';
const char *myptr = &ch;
*myptr = 'b' <---- Possible
myptr++; <-----Not Possible

Const char *myPointer is a non constant pointer to constant data; while char *const myPointer is a constant pointer to non constant data.
