Yes, in C, the array name represents the first address of the array, because it is a pointer constant pointing to the first element of the array.
#Does the array name in C represent the first address?
Answer: Yes.
Detailed explanation:
In C, the array name is a pointer constant pointing to the first element of the array. Therefore, the array name is essentially an alias for the first address of the array.
Example:
<code class="cpp">int arr[10]; // 声明一个 10 个元素的整型数组 cout << &arr[0] << endl; // 输出数组首地址 cout << arr << endl; // 输出数组名,它本质上与 arr[0] 的地址相同</code>
Output result:
<code>0x100 0x100</code>
This example shows that the array namearr
and the first address of the array# The values of ##&arr[0] are the same, so the array name represents the first address.
Note:
Although the array name points to the first address of the array, it cannot be modified to point to other addresses. This means that the array name is a constant pointer.The above is the detailed content of Does the array name in C++ represent the first address?.
