About the definition of pointer variables (personal notes)

#include <stdio.h>
int main()
{
    char f='A';
    int b=123;
    
    char *pa=&f;/* Define a character pointer address variable *pa： The function is to point to an address
     Now? *pa Pointing at f The address of this variable , And there is a variable in the address of this variable A*/
    int *pb=&b;// Empathy  
    
    printf("%c\n",*pa);
    printf("%d",*pb); 
    return 0;
}

// *pa It's a pointer variable ( It's an arrow , Used to point to )

// *pa=&f It is this pointer variable that now points to f This address , You can change the variables in this address

/* Imagine having two rooms , One room is f , The other room is pa Now? f There is... In the room
    A This man , The use *pa=&f said pa There can also be... In this room A This man , Do you use
    *pa=& other that ,pa This room will allow other In this room */
