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?

#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>
Copy after login

Output result:

<code>0x100
0x100</code>
Copy after login

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.
