1) Consider the array declaration, int x[20];. There is no memory allocated for x[20].

2) Given the two C++ array declarations:

int a[10], b[10];

You can successfully compute one array, say a, then assign b to a:

a = b;

3) Give the syntax of an array declaration. Mention the base type and declared size.

4) The dot operator is used between an object and a data member or between a calling object and a call to a member function from the class of the object.

5) You can change the behavior of + for the int type using operator overloading
