Abstract: I wonder if anyone else feels that they can play with microcontrollers and drive various functional modules, but when asked to write a complete set of code, it lacks logic and structure, starting off with random copying and pasting! This indicates that programming skills are still at a relatively low level. So how can … Read more
1 Introduction to Function Macros Function macros are macro definitions that contain multiple statements, typically encapsulating frequently called functionalities without the overhead of function calls, such as stack push and pop. Function macros are essentially macros and can be defined directly, for example: #define INT_SWAP(a,b) \ int tmp = a; \ a = b; \ … Read more
C Language String Handling Techniques: How to Efficiently Operate on Character Arrays In C language, strings are stored as character arrays. Although C does not have a built-in string type, we can efficiently handle strings using character arrays and some standard library functions. This article will introduce some commonly used string handling techniques and provide … Read more
