How are arrays in C language allocated in memory?

The method of allocating C language arrays in memory: First, the corresponding header file is the iostream stream responsible for input and output; then create an array in the main function, and use the cout statement to output the location of each element in the memory. Address; finally click the Run button to compile, link, and generate an executable file.

How to allocate C language arrays in memory:

1. First, we open the C language compiler, You can choose software such as Visual Studio, Code::Blocks or Dev-C. Here is Visual Studio as an example. Wait for the entire program to be completely loaded into the memory

2. Due to VS It is managed through solutions, so first create a new solution. If there is an existing solution, you can continue to use it, and then create a new project. Since we are debugging a command line program, we need to select the Windows console here. Application

3. After ensuring that the project name is correct, click the OK button. You will see that we have successfully created a project, and then right-click in the project list to add A C file, as shown in the figure after adding it

4. First, we include the corresponding header file, which is the iostream stream responsible for input and output, and set the default The namespace is std

5. Then in the main function, create an array. Here we take a double-precision array as an example. The length is 10 and assign initial values ​​to it. , since the array name identifies the address of the head pointer, if you do not use the array name, you need to use the pointer form to create other types of variables.

6. Then we use cout The statement outputs the address of each element in the memory respectively. Note that you need to add the address & operator. If you are using C language, you can use the printf function to output

7. Confirm After the code is correct, click the run button to compile, link, and generate an executable file. After a moment, we see that the output result is a hexadecimal address value. The address of each two consecutive array elements differs by 8, which means that it is in 64 Each double type data is stored in 8 bytes on the Win10 platform.
