关于C/C++的指针

 1. 数组和指针作为函数的参数的注意点：将数组作为参数的时候，会被转化成指针,例子如下：

 

#include <iostream>
using namespace std;

 

char fo[] = "foliage";

void my_arr_func(char foliage[10])
{
     cout << "address of array param is : " << &foliage << endl;
}

void my_pointer_func(char* foliage)
{
     cout << "address of pointer param is : " << &foliage << endl;
}

int main()
{
    cout << "address of array param is : " << &fo << endl;
       
    my_arr_func(fo);
   
    my_pointer_func(fo);
   
    system("PAUSE");
    return 0;
}

 

 

 

2.区别下面代码：

（来自C专家编程）

func(int arr[])

{

     arr[1] = 3;

     *arr = 3;

     arr = arr2;

}

 

----------------------

int array[100],array2[100];

main()

{

     array[1] = 3;

     *arr = 3;

     array = array2; /*failed*/

}
