Key Summary：After a function call, the operation is performed on the initialized parameter, not the argument!Function Parameters and ArgumentsIn C language, depending on the different states of the function, the parameters can be roughly divided into two categories: one is formal parameters, and the other is actual parameters.Formal parametersare the parameters declared in the function … Read more
Function Parameter Passing MethodsIn C language, the methods of passing function parameters can be roughly divided into two types: one is pass by value, and the other is pass by address.Pass by ValuePass by value, as the name suggests, means passing the value of the actual parameter, and it is a copy of the value. … Read more
Pointers Detailed Explanation (Pointers） In the C programming language, a pointer is a powerful tool that allows you to directly manipulate memory addresses. Understanding pointers is not only key to writing good C programs but also fundamental to grasping core concepts such as memory management, arrays, and function parameter passing. 1. What is a Pointer? … Read more
