is the size of the array changeable

can we change the size of the array? in other words, if we intialize the array size to a size, say 10 elements, later in the process we might have to store something more than 10 elements. Can the size of the array automatically expand?

Thanks.

Not a standard array. In this case, you must create an array of a larger size, copy the elements over, and deallocate the old array (c++). In C using malloc/free, you can call realloc() to resize dynamically allocated memory.

In C++, it is better to use some sort of STL container, such as a vector. vectors will grow in size automatically.
