How do I convert a std::vector<double> to a double array[]?
207
Using the transform() function to convert vector to array in C++ We can use the transform() function in C++ to apply a function to all the elements of an array. It applies the function to all the elements and stores the result in a new array.
It is a row of data. An array is a list that is arranged in multiple dimensions. A two-dimensional array is a vector of vectors that are all of the same length. We see that A has three rows and four columns and that each row is one of the vectors in the list.
There's a fairly simple trick to do so, since the spec now guarantees vectors store their elements contiguously:
std::vector<double> v; double* a = &v[0]; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
