Pointer introduction, mouse pointer Pointer: 1. Declare a pointer of the int type and assign a value.   2. assign values directly in the Declaration.   Iii. NULL pointer   4. Floating pointer wild pointer:   A floating pointer is essentially a

Implementation of scanf functions using variable parameters in C Language Since the printf function variable parameter is implemented, the scanf function variable parameter must be implemented. The source code is as follows: This source code does

Variable parameters in C Language The function of variable parameters in C language is really very large. Since I published an article on how to implement printf, fprintf, and sprintf, many bloggers have asked me about the mechanism, I also

Implementation of square root Computing Algorithm in Linux kernel using C language The square root calculation is also implemented in the Linux kernel, just like the sqrt function in the math. h mathematical library. Square root formula

C language insertion sorting The essentials of the insert sort method are to insert each read number to the final storage array immediately, and each insert will make the array orderly. Code:   # Include # Include # Define n 10

C language selection and sorting Select-based sorting is a relatively understandable sorting algorithm. Assume that you want to sort the sequences with n numbers in ascending order. The algorithm steps are as follows: 1. Find the subscript of the
