Why must a pointer to a char array need strcpy to assign characters to its array and double quotes assignment will not work?

In the first example you are chaning the value at, in the second you are changing the value of what at points to. Assigning a char * to a double quoted string assigns it to a static const pointer.

In particular, in the first example at now points a different location in memory.
