This is something I have wondered for a long time. Take the following example: struct matrix { float data[16];
I answered the question about std::vector of objects and const-correctness, and received a comment about undefined behavior. I do not agree and therefore I have a question.
I want to overload the assignment operator for types like \"int\", \"long\" etc.That is, I want to use code like:
Every time I assign a string, I\'d actually like to assign a string object, without the extra code. This var foo = \"bar\";
I have encountered the following problem which proved to me that I know far too little about the workings of C++.
I want to enforce explicit conversion between structs kind of like native types: int i1; i1 = some_float; // this generates a warning
I am trying to use a if condition to assign a value to a variable in an xquery. I am not su开发者_如何学编程re how to do this.
This question already has answers here: What are the differences between "=" and "<-" assignment operators?
I have written a overloaded assignment operator of class perform copying all the variable values. For ex :in Exp.cpp
What is the copy-and-swap idiom and when should it be used? What problems does it solve? Does it change for C++11?
