    [RESOLVED] Array Question

    Hello,

    I'm just learning arrays and I had a quick question on how the computer sees them. I wrote this quick code on printing a number from the array. Why does it call the second array element when I enter a 1 by the array?

    Code:
    #include <iostream>
    using namespace std;
    
    int main() 
    {
    
        int adam[5] = {66,75,2,43,99};
    
        cout << adam[1] << endl;
    
    }
    Thank you!

    Re: Array Question

    Because the array index starts at 0 and not 1. To display 66 you would use adam[0]

    For a 5 element array, the indexes are 0 to 4 NOT 1 to 5.
