C Expert Programming Chapter 4 The Shocking Fact: Arrays and pointers are not the same 4.4 Matching declarations to definitions

/* Match declaration with definition */
//File 1:
int mango[100];
//File 2:
extern int mango[];
/* The definition of the mango array allocates space for 100 ints.*/
...
/*Refer to some code in mango[i]*/
int *raisin;
/*Apply an address to accommodate the pointer.The name of the pointer is raisein, and it can point to any int variable (or int array).
*The pointer variable raisin itself is always located at the same address, but its content can be different at any time, pointing to different addresses
*Int variables of *, the address of the mango array cannot be changed, at different times heThe content can be different, but it always represents 100
* contiguous memory spaces.
