Whether in C or C ++ code, the word typedef is widely used. Of course, the frequent occurrence is still in C code. Typedef is similar to # define, but it is more different, especially in some complicated usage, I read some blogs of C/C ++ learners

  This learning is to use the rootviewcontroller class in the navigation-based application template to set the operation method and use the uitableview attribute value. Add a navigation bar to the window of the program in the navigation controller

Usage and difference between typedef and # define I. Usage of typedef In C/C ++, typedef is often used to define an alias for an identifier and a keyword. It is part of the language compilation process, but it does not actually allocate memory

Data typeThe Java programming language defines eight basic data types (see), divided into four classes: integer classes (byte, short, int, long), text Class (char), floating-point class (double, float), and Logical Class (Boolean).1. Integer class(1)

A typedef is the meaning of a type definition. typedef structs are designed to facilitate the use of this structure. The specific difference is that if struct node {} is defined as a struct. This is required when applying the variable for node,

typedef is used to define the data type, there are several usage 1char* PA, PB; It only declares a pointer to a character variable, and a character variable;The following are possible:typedef char* PCHAR;PCHAR PA, PB;This usage is very useful,

One, the code1 //input A, B; output a larger value; If same, output 02 3#include 4 5 intMaxint,int);//c when calling a function, if the called function is defined earlier, it does not need to be declared, and if the called function is defined later,

Ask simple code questions. The following code output is confusing. the code result is $ value & quot; 100 & quot; bool (true) $ valuetrue. the code is as follows: $ value & quot; 100 & quot; define the character variable as 100 echo & quot; $ value &
