I will be modifying the contents of the structure. With the first function, I would create the structure and do a shallow copy, which I guess is a rather silly method. I suppose it would get much...

For a program I am working on, I need to perform some operations on vectors, such as vector addition. However, I am unsure of how best to write the functions to perform the operation. My vector is...
