#include #include #include /* Valarrays STL was embedded since C++98 for a well data managing and processing. Beside vectors, queues, deques, lists, stacks, an independent library called valarray. This last one is a numerical support array, for more flexible processing num-datas. It supports element-wise mathematical operations and various forms of generalized subscript operators, slicing and indirect access. As compare to vectors, valarrays are efficient in certain mathematical operations than vectors also. (Source : https://www.geeksforgeeks.org/std-valarray-class-c/) There is the following instance of processing valarrays at basically : */ int main() { std::valarrayarr={1,2}; std::valarrayarr2; std::valarrayarr3; int summation(0),maximum(0), minimum(0); arr2=arr.apply([](int a){return a+=2;}); //The apply method (with an Encapsulated Lambda as example) /* Unlike almost any other standard library function that takes a form of predicate or other callable object, for example std::valarray::apply function actually only takes an actual pointer to a function, and not using templates to accept anything callable. A capture-less lambda can be converted to a pointer to a function, like what the apply function needs. But if you use captures in your lambda then that's not possible anymore.
