复习一下C指针

void (int *p){
    p = p + 1;
}
void inc_ptr_2(int *p){
    *p = *p + 1;
}
void inc_ptr_3(int **p){
    *p = *p + 1;
}
int main(){
    int A[3] = {50, 60, 70};
    int *q = A;
    inc_ptr_1(q);
    printf("*q = %dn", *q); 
    inc_ptr_2(q);
    printf("*q = %dn", *q); /*51*/
    inc_ptr_3(&q);
    printf("*q = %dn", *q); /*60*/
    return 0;
}
