Android c++函数的相关内容

Android C++系列：C++11函数特殊特性

1. 背景在Python中函数有默认参数等，在C++11中我们发现C++也支持了默认参数；还有C++特有的内联函数、constexpr函数等知识都有不少细节，本文对这些知识做详细介绍。2. 默认参数我们在Java中重载函数时经常有这样的形式：public CustomView(Context ...

Android C++系列：函数返回值注意事项

1. 背景函数返回值就是使用return语句终止正在执行的函数，看是很简单的问题有什么说的呢？因为越是简单的问题里面越是有一些不易发现的坑。比如在循环中使用return语句：bool findChar(const string &str, const char c){ auto size =...

Android C++系列：数组在函数中注意事项

1. 背景数组作为函数形参传递的是数组首元素的地址本来是很简单的知识点，但是在具体使用中还会有一些坑需要注意。2. 数组做函数形参C++中数组有两个特殊的性质：不允许拷贝数组：我们不能将数组的内容拷贝给其他数组作为初始值，也不能用数组为其他数组赋值，所以我们不能以值传递的方式使用数组参数；使用数组....

Android C++系列：函数知识知多少

1. 背景函数可以理解为功能的封装，很基础的功能单元，但是因为它虽然看似简单，但是里面涉及了不少知识点和技巧，我们花一篇文章来整理。2. 函数定义函数有以下几部分定义：返回类型函数名称形参列表函数体函数调用的形式是函数名(),函数调用过程涉及到控制权转移。函数体其实是一个语句块，语句块会涉及到作用域...

Android C++ 系列：Linux Socket 编程（二）网络套接字函数

1. socket#include <sys/types.h> /* See NOTES */ #include <sys/socket.h> int socket(int domain, int type, int protocol);domain:AF_INET 这是大多...

Android C++系列：C++最佳实践1虚函数

1. 背景C++多态的核心技术基础就是虚函数，虚函数允许我们使用同样的基类指针调用同一个方法的不同实现版本。我们Android使用Java开发过程中，方法重写技术自动实现了多态，C++角度可能更繁琐一些，本文从Java程序员思维角度来阐述C++虚函数及开发过程一些准则。2. 什么是虚函数在Ja...

Android C++ 系列：Linux 常用函数和工具

1. 时间函数1.1 文件访问时间#include <sys/types.h> #include <utime.h> int utime (const char *name, const struct utimebuf *t); 返回:若成功则为 0,若出错则为- 1如果ti...

Android中是否有类似于C / C ++中“ int main”的函数，其中包含程序的主循环？

通常，在C或C ++程序中，通常会有一个主循环/函数int main ()。我可以在android Java开发中使用类似的功能吗？
