指针（4）指针数组 #include <iostream> using namespace std; const int MAX = 3; int main () { int var[MAX] = {10, 100, 200}; for (int i = 0; i < MAX; i++) { cout << "Value of var[" << i << "] = "; cout << var[i] << endl; } return 0; } Value of var[0] = 10 Value of var[1] = 100 Value of var[2] = 200 指向整数的指针数组的声明： int * ptr [ MAX ]; 把 ptr 声明为一个数组，由 MAX 个整数指针组成。因此，ptr 中的每个元素，都是一个指向 int 值的指针 #include <iostream> using namespace std; const int MAX = 3; int main () { int var[MAX] = {10, 100, 200}; int *ptr[MAX]; for (int i = 0; i < MAX; i++) { ptr[i] = &var[i]; // 赋值为整数的地址 } for (int i = 0; i < MAX; i++) {
