Problem:Detects if the sum of two numbers in the array is equal to a numberWorkaround One: Sort the array first, and then start traversing from both endsAfter the array is sorted, the minimum value is taken from the left end, and the maximum value

Many algorithms are defined in the C++11 standard, which allows us to operate a variety of containers and arrays conveniently, and it is important to note that these algorithms operate not as containers, but as iterators, and then manipulate the

Learning the Observer pattern again today inspired my thinking. The process monitoring program has written a few before, which is a different way of thinking, using delegates and events to implement. I have used the serial number to mark the key

string strparam = request.params["param"]; if NULL { strparam"";} string strparam= request.params["param"null"": request.params["param"];？：就是一个三元的操作符。利用这个三元操作符也称条件操作符，就很简单的把一个if语句给实现了。在使用条件操作符的时候要注意，假定条件表达式是这样 x？y：z，表达式类型的只能是使y 和z的变量类型之一，换句话说就是
