回调函数是做为参数传递的一种函数,在早期C样式编程当中,回调函数必须依赖函数指针来实现。 而后的C++语言当中,又引入了 std::function 与 std::bind 来配合进行回调函数实现。 标准库中有大量函数应用到了回调函数,其中 std::sort 就是一个经典例子。 一,回调函数 回调函数的创建步骤大概为: 1,声明一个函数指...
A function is block of code which is used to perform a particular task, for example let’s say you are writing a large C++ program and in that program you want to do a particular task several number of times, like displaying value from 1 to 10, in order to do that you have to wri...
