Hello, I'm Chen Meng~ After a few months, I met you again. It's close to the end of the term. I'm really busy recently. Today, I want to share with you the ATM code. Although there is a lot of code, it is not difficult. If you want to understand the soul of C language - pointer, you may be disappointed. My article is suitable for novices. How t ...

Click like before copying 6-1 Experiment 7_ 11_ Cyclic shift (100 points) Design function void shift (int * array, int num, int size);, Realize the circular movement of elements in an integer array to the left by several positions. The meaning of cyclic shift to the left is as follows: For example, the original array a [0], a [1] The eleme ...

Solving the maximum common divisor In the foundation of C language, one of the most common problems is to solve the maximum common divisor. First of all, we need to know what the maximum common divisor is (those who have studied in primary school should understand it). I won't go into details here. Secondly, we need to use the most basic code ...

poll function poll is a function in the character device driver in Linux. poll is essentially no different from select. It copies the array passed in by the user to the kernel space, and then queries the device status corresponding to each fd. If the device is ready, add an item to the device waiting queue and continue to traverse. If no r ...

Pointer Initializing pointer variables A pointer is a variable whose value is a memory address. Just as the value of a char type variable is a character, the value of an int type variable is an integer, and the value of a pointer variable is an address. To create a pointer variable, first declare the type of the pointer variable. int *pi; / ...
