structure Second-level pointer type name * * Variable name2. Learning experience.Learning to the back has been a bit esoteric, especially the two-level pointer, a little around the bend, and write a system is really not easy, to consider all aspects, sometimes realize this function, you can not achieve another function, it is necessary to re-frame, delete the change, changed the deletion, but also will appear a bunch of mistakes to read, And the compilation is not the same as your own expec

There can be no spaces in the middle of a 1.3.3 macro name. 1.4 Dynamic allocation through the function malloc () can dynamically allocate the corresponding size of memory units, using the dynamic allocation of memory to process multiple strings, can be based on the actual input of the amount of data to re

*ptr) , must provide the starting address of the memory, and no return value.Note: malloc is paired with free, and the compiler does not help us release memory, so remember to release it once you have applied dynamic memory. 2. Learning ExperienceThis week wrote a student Information management system project, did a lot of days, code volume also reached 278 lines, feel the difficulty of writing is still a bit big, especially in the robustness of the project, so I have to change a lot of in

pointer, a variable for holding a level two pointer is called a two-level pointer variable. According to the different cases of B, the level two pointer is divided into pointers to pointer variables and pointers to arrays. 2. Learning Experience Two-dimensional pointers are upgraded versions of pointers, which are more difficult to understand and require special attention to pointer pointing problems It's quite a challenge to build a project, but it's a step-by-step.

Learn about the week1: This week the newly-learned content has recursion, in which recursion to notice must have recursive exit, recursive expression: such as fact=n*fact (n-1);2: There is the teacher taught how to build the project, although not successful, but the basic operation still understand3: Then you learn the pointer array, pointe

, which is the important point of recursion.V. Summary of the study this Week 1. Introduce this week's learning content 1. Learn basic function nesting calls, know how to make the code more readable, and realize the complex problem of structured program. 2. Recursive exit and recursive formula in recursive function is the main point, master the relationship between the equation can not delve into the process, otherwise it will be chaotic. 3.

And the code is small, the words are simple and frightening This week's study summarizes this week mainly to learn the big program structure The goal is to prevent the code from being too long to break it into multiple functions 1. c files are a compilation unit, and the compiler processes only one compilation unit per compilation So to build a project, add a number of source code, the compiler will all the source code files are compiled and linked together The fun
