My results for multiple times are still the fastest in memset, But it is said on the Internet that the for () loop initialization array is faster than memset (under INT), because memset can only operate on one byte at a time. I don't know what the results are, or the principle of my testing program is wrong?

This article describes several related aspects of the Java array, describing the declaration, creation, and initialization of the Java array, and giving its corresponding code.the declaration mode of one-dimensional array : type var[]; or type[] var;
You cannot specify its length (the number of elements in an
Initialize an array when it is declared, as shown in the following example:int[,] MyArray = new int[,] {{1,2},{3,4},{5,6},{7,8}};Initialize the numbers without specifying a level:int[,] MyArray = {{1,2},{3,4},{5,6},{7,8}};Declaring an array variable without initializing it must be assigned to this variable using the new operator array.int[,] myArray;MyArray = new int[,]{{1,2},{3,4},{5,6},{7,8}};MyArray = [,
The input and output of a character array can be in two ways:1) Input output by character, as example 5.9.2) input or output the entire string at once. For example, the following program segments are available:Char str[20];cin>>str; Enter a string with a character array namecoutEnter a string at run time, such as:ChinaIn memory, the array str is shown in state 5.
How to declare a one-dimensional array:
Type var[]; or type[] var;
You cannot specify its length (the number of elements in an array) when declaring an array.
Use the keyword New in Java to create an array object in the following format:
Array name = new

What is the application of C # array initialization in data compression? We often use arrays. All elements of the array need to be zeroed at every point. Because C # does not provide a memset () method. So let's try the following test.
