If you know the size at compile time, you could use C++11's std::array aggregate.Sat, 04 Apr 2026 12:10:00 GMThttps://stackoverflow.com/questions/28663299/declaring-a-2d-vector61 std::vector has a fill constructor which creates a vector of n elements and fills with the value specified. a has the type std::vector<std::vector<int>> which means that it is a vector of a vector. Hence your default value to fill the vector is a vector itself, not an int. Therefore the second options is the correct one.Wed, 01 Apr 2026 04:07:00 GMThttps://stackoverflow.com/questions/3701903/initialisation-of-static-vectorI wonder if there is the "nicer" way of initialising a static vector than below?Thu, 02 Apr 2026 11:08:00 GMThttps://stackoverflow.com/questions/4268886/initialize-a-vector-array-of-stringsWould it be possible to initialize a vector array of strings? for example: static std::vector&lt;std::string&gt; v; //declared as a class member I used static just to initialize and fill it with s...Thu, 02 Apr 2026 04:05:00 GMThttps://stackoverflow.com/questions/2236197/what-is-the-easiest-way-to-initialize-a-stdvector-with-hardcoded-elementsBut you are right that if you want to initialize an empty vector and a non-empty vector you will have to use different constructs. Since C++11 this is a non-issue as you can use the initializer list constructorThu, 02 Apr 2026 06:07:00 GMThttps://stackoverflow.com/questions/508374/what-are-vectors-and-how-are-they-used-in-programmingThis pair (3, 4) is also a mathematical vector. In programming, this name "vector" was originally used to describe any fixed-length sequence of scalar numbers. A vector of length 2 represents a point in a 2D plane, a vector of length 3 represents a point in a 3D space, and so on.Wed, 01 Apr 2026 21:03:00 GMThttps://stackoverflow.com/questions/9694838/how-to-implement-2d-vector-arrayI'm using the vector class in the STL library for the first time. How should I add to a specific row of the vector array? struct x { vector <vector <int> > v; int row; }; ve...Sat, 04 Apr 2026 05:29:00 GMThttps://stackoverflow.com/questions/35501439/array-of-vectors-or-vector-of-arraysYou have to define N at compile-time, and all vectors will be placed on the stack †, however, each vector will allocate elements on the heap. I'd always prefer vector of vectors case (or the matrix, if you could use third-party libraries), or std::array of std::array s in case of compile-time sizes.Fri, 03 Apr 2026 23:52:00 GMThttps://stackoverflow.com/questions/2392308/c-vector-of-char-arrayThe vector of vectors fits many purposes, but is not the answer and in some cases it is just wrong. Is an unpleasant experience to fall in the trap of fixing errors caused by not understanding clearly the difference between arrays and pointers, or between multidimensional arrays and arrays of arrays.Thu, 02 Apr 2026 13:17:00 GMThttps://stackoverflow.com/questions/52405495/define-a-symbolic-unit-vector-in-sympyLet say I want a n -component symbolic real unit vector, where n can be any integer number, let say n=3. That is: So far I'm stacked at this very basic point: v = Matrix(symbols("v:3", real=True)) How can I code the normalization condition?Wed, 01 Apr 2026 00:10:00 GMT
