C + + one-dimensional arrayDefining a one-dimensional array
The general format for defining a one-dimensional array is:Type identifier array name [constant expression];For example:
int a[10];
It represents an array named A, which is
Zookeeper
I. Two-dimensional array Initialization
The two-dimensional array initialization form is:Data Type array name [whole constant expression] [whole constant expression] = {initialization data };The initial values of each array
The storage method of a two-dimensional array is no different from that of a one-dimensional array. But how can I write the parameters of a two-dimensional array? Note that the form parameter in the function is actually equivalent to a declaration
I. Multi-dimensional array address Representation
There is an integer two-dimensional array a [3] [4] as follows:
0 1 2 34 5 6 78 9 10 11
Set the first address of array a to 1000, and the first address and value of each subscript variable.
As
In Java, arrays are regarded as an object.
When defining an array, there are two defining methods: int [] A and int A []; the second is the way C/C ++ defines the array, we recommend that you use the first definition method for Java.
General
# Include "stdio. H"
Void main ()
{
Char * str1 [2] [2] = {"FF", "F9", "Fa", "F9"}; // initialize a Two-Dimensional String Array
Char * STR; // defines a one-dimensional string variable.
Int A, B;
Int I, J;
Int result1;
For (I = 0; I
{
For (j = 0;
In Java, an array is considered an object
When you define an array, there are two definitions: int[] A and int a[]; the second is a C + + array-defined method, with the first definition of Java recommendations.
The general principle: any object must
Recently read the "Linux C programming Encyclopedia" this book, although there are some mistakes in the book, but overall, the writing is still good.When I see the network Programming "section 23.2.4 to obtain host information", encountered a piece
Use a single loop to initialize a multi-dimensional array
For programmers, the most commonly used multi-dimensional arrays are two-dimensional arrays and three-dimensional arrays. The method and essence of multi-dimensional arrays are similar. Here
Recently, I am working on matrix operations. Based on previous lazy ideas, I want to directly create a function that can transmit a matrix of any dimension for calculation. Therefore, the void matrix_mult (float ** p) function is declared ); Then,
