An array of definitions.
There are two ways to define an array:
1, var arr1 = []; Define an empty array
2, var arr2 = [1,2,3, "str1", "str2"]; Defines an array that has 5 elements.
3, var arr3 = new Array (3); Define an empty array
4, var arr4 =
Today I encountered a pointer array, understanding the channel data for half a day ...BOOLLocalfilesaver::saveadcdata (Cash *data, LPCTSTR folder) { if(_tcscmp (folder, _t ("")) ==0) { return false; } TCHAR Path[max_path]= {0 }; TCHAR
"title"?There is an integer array of arr and a window of size w that slides from the leftmost edge of the array to the far right, and the window slides one position at a time to the right.For example, the array is [4,3,5,4,3,3,6,7] and the window

Array pointer (also called row pointer)define INT (*p) [n];() A high priority, first of all, that P is a pointer to a one-dimensional array of integers, the
Break and continue use range:
Continue can only be used for looping structures, meaning that there must be loops as long as there is continue.
Break is used in switch statements and loop structures.
When break and continue exist
To assign a two-dimensional array to a pointer, you should assign this value:int a[3][4];int (*p) [4]; The statement defines an array pointer to a one-dimensional array with 4 elements.P=a; Assign the first address of the two-dimensional array to p,
Array Pointers: A pointer to an array, pointer to arrayArray of pointers: array of pointer, which is used to store pointers to arrays where array elements are pointersInt (2) [6] Array pointer: Represents a pointer to array a element representation:
To assign a two-dimensional array to a pointer, you should assign this value:int a[3][4];int (*p) [4]; The statement defines an array pointer to a one-dimensional array with 4 elements.P=a; Assign the first address of the two-dimensional array to p,
First, define the array.There are two ways to define an array:1, var arr1 = []; Define an empty array2, var = [arr2, "str1", "str2"]; Defines an array of 5 elements.3, var arr3 = new Array (3); Define an empty array4, var arr4 = new Array ("str1",
Array pointers (also called row pointers)define INT (*p) [n];() high priority, the first explanation is that p is a pointer to an integer one-dimensional array, the length of the one-dimensional array is n, it can be said that the step of P. In
ArrayExample: If there are now 10 people lined up as a team "Zhang San, John Doe, Harry ...", the team called a, and then asked the first person from 0 to count off "Zhang three newspaper 0, John Doe 1, Harry 2 ...". Now ask the first person to
PHP converts a one-dimensional array to a two-dimensional array of 3 consecutive values, a two-dimensional array of dimensions
The example in this paper describes the PHP implementation of converting a one-dimensional array into a two-dimensional
Array: Each item in the arrays can hold any type of data, and the size of the array is dynamically adjusted (can contain up to 4294967295 items, approximately 4.3 billion items)[1.1] Array creation:[1.1.1] Use the array constructor (you can also
Array pointers (also called row pointers)define INT (*p) [n];() high priority, the first explanation is that p is a pointer to an integer one-dimensional array, the length of the one-dimensional array is n, it can be said that the step of P. In

Today review code, see some uncle in the generic string type of a collection or array of string type into a comma-spaced strings form when still only focus on the results do not pay attention to the process, "Big uncle" can we take
In actual work, there is a class A that now needs to use pointers to multiple a objects, and this is when the first thought is an array of pointers.
