A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

A Static class will always have the static constructor and its called only once since after that its in the memory for its lifetime. A Static class can contain only static members. So all the members and functions have to be static. ...

static void __attribute((section("__TEXT,MySection" ))) myFun1(void){ print(""); } attribute((unused)) function attribute attribute((unused)) 其作用是即使没有使用这个函数,编译器也不警告。 attribute((used)) function attribute attribute((used)) 其作用是告诉编译器避免被链接器因为未用过而...
#include<stdlib.h>#include<stdio.h>staticvoid__attribute__((constructor))beforeMain(void){printf("Before main...\n");}intmain(void){printf("Main!\n");return0;} 输出结果 为什么最开始执行的不是main函数?怎么和我们刚开始学习C程序时说的不一样呢?从运行结果中,我们可以看出来beforeMain是在进入...
方法前面的 +/- 号代表函数的类型:加号(+)代表类方法(class method),不需要实例就可以调用,与C++ 的静态函数(static member function)相似。减号(-)即是一般的实例方法(instance method)。 这里提供了一份意义相近的C++语法对照,如下: classMyObject:publicNSObject{protected:intmemberVar1;// 实体变量void*membe...
