I have a container of std::shared_ptr.I want to compare two containers using std::equal.The class A has operator== defined.I want equal to compare if each element is equivalent using its operator==, n
Why this condition is never true ? Both parts of the equation are integers, so there must be equality for index = 0, 10, 20, 30, 40. I am compiling this code using g++.
I am building some prepared statements that use parametrized values. As an example: SELECT * FROM \"Foo\" WHERE \"Bar\"=@param
开发者_C百科>>> class foo(object): ...def test(s): ...pass ... >>> a=foo() >>> a.test is a.test
I\'m wondering if I should always use \"===\" (strict equality) when doing equality checks... Is there any example of when it is preferable to use \"==\" (non-strict equality)? In particular, should:
Until today, my understanding of .NET Tuple classes had been that they delegate their implementation of Equals() to their contents, allowing me to equate and compare them \"by value\".
I\'m using a third party library containing a class which lacks both operator==() and Equals(). I\'d like to implement one myself, but I\'m not sure how to name it and where to put it. I\'ve tried to
if (typeof a !== \"object\" && typeof b !== \"object\") { return a == b; } ... // check pairwise equality of object a & b using `for in`
Sometimes I have structs such as this -- struct aggregate1 { std::string name; std::vector<ValueT> options;
In code, why wouldn\'t this work?开发者_开发百科 intMax = intTopValue = 20 This is interpreted as intMax = (intTopValue = 20).
