C++ STL 2D Vector: Here, we are going to learn about the vector of vector or 2D vector in C++ STL, its declaration with user defined size.

Using namespace std::vector::insert(), it will extend the vectors by using to insert the new elements at the correct positions in the vector containers. The elements are being inserted into the container. If the element value is inserted into more in the containers, it automatically increases...

A particular data type is defined at the time of vector declaration. If the vector size is not defined then the vector is called an empty vector. The size of the vector can be changed by using different methods or initializing the vector. ...

That's a quick overview on how to implement a performant and easy-to-use dynamic data structure in C. This structure can be used as a fundamental building block in many programs. The implementation has been kept simple because frankly, it doesn't have to be more complicated. New functions...
How to do forward declaration of vector in a header file. Nov 7, 2014 at 2:44pm srgnuclear (6) Hi, I have a header file in which we include vector at the top. But we want to remove that include. On doing so I get compilation errors as the header file uses std::vector<> at...
Vector Register Declaration Just use themipp::Reg<T>type. mipp::Reg<T> r1, r2, r3;//we have declared 3 vector registers But we do not know the number of elements per register here. This number of elements can be obtained by calling themipp::N<T>()function (Tis a template parameter...
The SIMD directive does not tell the compiler whether the target of the pointer has unit stride, so there are still two loop versions. If you know that the target always has unit stride, then add the “CONTIGUOUS” keyword to the pointer declaration to inform the compiler, which will then...
