In Objective-C, attributes combine new pre-compiled commands and new attribute access syntax. The new attribute function significantly reduces the number of lengthy code that must be written. Next we will compare the following code to copy the code /

Core tips:All the complex pointer declarations in C language are made up of various declarations nested. How can we interpret complex pointer declarations? The left-right rule is a name-and-use method. All the complex pointer declarations in C

I recently posted a question on OJ of Nanyang sci-tech. I found that most of the answers to a question that is interesting on the Internet use stacks. Unfortunately, I have not learned the data structure yet, therefore, it can only be solved in a

Two special Operators related to pointers: 1. "&" the address operator can be used to retrieve the addresses of common variables; 2. "*" has two meanings: 1. pointer flag: whether the pointer flag is used depends on whether there is a type in the

Next, the previous article >, Continue to learn how to design and use assertions to make it easier and more effortless to automatically find errors in the program. First, let's look at a simple compression and restoration program: Byte *

1. What is alignment and why:1. in modern computers, memory space is divided by byte. Theoretically, it seems that access to any type of variables can start from any address, however, the actual situation is that access to specific variables is

How do you understand the process orientation? What if I understand the concept of a function?As we all know, C language is process-oriented. How can we embody these processes in the process of writing code using C? In my understanding, we use

Delegate In ios development, we often use a dialog box similar to the following: Therefore, we are very familiar with the following code: -(IBAction) showSheet :( id) sender {UIActionSheet * actionSheet = [[UIActionSheet alloc] initWithTitle: @

Author: Qing Dujun Method 1: Two functions are required to obtain the file size: fseek () and ftell () Fseek () function: Prototype:IntFseek (FILE* Stream,LongOffset,IntFromwhere ); Parameters: Stream: The first parameter stream is the file pointer.

1. each time a file calls an input/output function, a new ferror () function value is generated. Therefore, the ferror function value should be checked immediately after the input/output function is called, otherwise, the information will be lost.
