C++ Question (Arrays and memory)

Answer 1

@Ultrilliam I found the answer. I thought it would be nice to share.

In C++ when we say int array[5], we are giving the array the size of 5, but from 0 to 4 only. So, 0, 1, 2, 3, 4, which are five of them. Anything beyond that is considered not in the scope of the array size and will probably return garbage value.

Also, if you declare an array , int array[5], but you Do not give each array values such as array[0] = 2;
array[1] = 11;
.
.
.
array[4] = 100;

Then the program does not know what exists at that memory when you print it out like this.

for (int i = 0; i < 5; i++){
cout << array << endl; } Output: Random garbage values (Ex. 97423625) which you never intended to use.

Answer 2

A slight correction:

for (int i = 0; i < 5; i++){
cout << array * << endl; }

Answer 3

The answer does not place an i inside [ ] in the front of array, but you get my idea.
