Pointer to an Array in C - An array name is a constant pointer to the first element of the array. Therefore, in this declaration,
I a 2D array say int a[2][3] when we call the function say add(a); we receive it using a pointer to an array void add(int(*p)[3]) BUT In 1D array say int b[5] we store address of array in a simple pointer to an integer int *p; p=b; my question is that w

Now, we can use pointers to point to the first character of an array of characters, and move through it. char*p2 ;//We use malloc to allocate 6 bytesp2 =malloc(6);printf("\n This is the address that pointer p2 is pointing at %d ", p2);//p2 is an address as well as a varia...
arr1 is an array of 8 pointers to integers. int (*arr2)[8]; 1. arr2 is a pointer (the parenthesis block the right-left) to an array of 8 integers. int *(arr3[8]); 1. arr3 is an array of 8 pointers to integers.

Well, in C, the name of an array, is actually a pointer to the first element of the array.Confused? Let's try to understand this better, and use our "memory address example" above again. The memory address of the first element is the same as the name of the array:...

看起来像是a类型从array of int转移到pointer to array of int,它变成了“可修改的左值”。但我的gcc 9.3.0说: error: assignment to expression with array type" 我很困惑。 赋值运算符应具有可修改的左值作为其左操作数 数组不是可修改的左值,因此将其放在赋值的左侧会违反约束。
