array传值和传地址

demo 

#include <stdio.h>

#include <iostream>
using namespace std;

void byValue(int array[6]) {
    array[3] = 8;
}

void byAddress(int *array) {
    array[3] = 18;
}

int main(){
    //as表示数组的首地址，&as[0]表示数组的第一个元素的地址，因而as==&as[0]。
    int as[] {1,2,3,4,5,6};
    byValue(as);
    // 8
    cout << "array[3] = " << as[3] << endl;

    byAddress(as);
    // 18
    cout << "array[3] = " << as[3] << endl;

    byValue(&as[0]);
    // 8
    cout << "array[3] = " << as[3] << endl;

    byAddress(&as[0]);
    // 18
    cout << "array[3] = " << as[3] << endl;

    //as表示数组的首地址，&as[0]表示数组的第一个元素的地址，因而as==&as[0]。
    cout << "as.address=" << as << endl;
    cout << "&as[0].address=" << &as[0] << endl;

    return 0;
}

输出

​array[3] = 8​

​array[3] = 18​

​array[3] = 8​

​array[3] = 18​

​as.address=0x7ffeefbff4f0​

​&as[0].address=0x7ffeefbff4f0​
