How to give size to vector
To answer your question, to change the size of a vector you can use the resize member function. std::vector myvector; myvector.resize (5); You can also use resize to initialize all the values. For instance, in the following example there are five 0's in the vector. WebLet’s now look at some examples. First, let’s set the length of the above vector to 3 and display the resulting vector. # set length of the vector length(vec) <- 3 # display the vector print(vec) Output: [1] 10 20 30. You can see that the vector here is shortened and the extra values (40 and 50) are removed from the vector.
