In C programming language, the concept of pointers is the most powerful concept that makes C stand apart from other programming languages. In the part-I of this series we discussed thefundamental concepts around C pointers. In this article, we will try to develop understanding of some of the ...
Array Of Pointers Just like any other data type, we can also declare a pointer array. Advertisement - This is a modal window. No compatible source was found for this media. Declaration datatype *pointername [size]; For example, int *p[5]; //It represents an array of pointers that ca...
type *name_of_pointer [size_or_array]; In the above syntax, if we want to create an array of pointers, then we have to first define the type of the array pointer; after that, we define the name of our pointer but remember always we define a pointer using the ‘*’ astrict symbol...
This article introduces how to declare an array of pointers to functions in Visual C++. The information in this article applies only to unmanaged Visual C++ code. The sample code below demonstrates building an array that contains function addresses and calling those functions. C++ Copy ...

In C, arrays are always accessed via pointers. If you try to pass an array by value, your code won't compile. While this is a good thing, keep in mind that you can update the underlying array, as we have seen with our batting roster. If you need to pass arrays to a function, ...
In C++, when you want to return an array from a function, you need to consider the limitations of the language. Directly returning an array is not possible because arrays decay into pointers when passed to functions. This means that the function cannot return the entire array as it would re...
int *(arr3[8]); // An array of int pointers. 2、 遍历数组,使用sizeof计算数组长度,之后遍历 #include <iostream> int main() { int arr[] = {1, 2, 3, 4, 5}; int length = sizeof(arr) / sizeof(arr[0]); for (int i = 0; i < length; ++i) ...
