Which is true regarding sizing of arrays and vectors? Appending an element to an array automatically resizes the array if necessary Appending an element to a vector automatically resizes the vector if necessary An array's size can be specified during declaration, but a vector's size cannot A vector's size can be specified during declaration, but an array's size cannot
how to do?
Introduction:
Arrays are collections of elements with a defined size that is determined at the time of declaration and cannot be modified at runtime. Arrays are allocated as a single continuous block of memory, with each element taking up a certain amount of space. An index, beginning with 0, is used to access elements in an array.
Vectors, on the other hand, are dynamic arrays that may be enlarged while the programme is running. Vectors are built on top of an array, but they include extra features like automated resizing and bounds checking. Vectors may be enlarged using the resize() function, and elements can be added or deleted with the push back() and pop back() methods.
