Explanation / Answer

5. We will get a compilation error stating that "incompatible types when assigning to type 'int[4]' from type 'int *'"
6. True
Arrays in C++ are actually just pointers in disguise! When an array is passed to a function, C++ passes a pointer to the rst element of the array. This way, the array does not have to be copied. Because the address is used, the function can change data outside the scope of the function.
7. True.
In this case allocation should be done in heap memory not stack.
8. It does not compile.
error: assigning to an array from an initializer list
a = {1,2,3,4};
9.Prints: 1 2 3 4 5.
10.It prints: 0 1 2 3 4
