Why C/C++ array index starts from zero?
As Array index starts with 0, so a[i] can be implemented as *(a + i).
If Array index starts with 1 then a[i] will be implemented as *(a+i-1) which will be time consuming during compilation and the performance of the program will also be effected.
So, it is better to start index of the array from 0.
A simple program of array is given -
Example Code
int main() {
int array[5] = {7, 7, 7, 6, 6};
for (int i = 0; i < 5; i++)
cout << *(array + i);
return 0;
}Output
7 7 7 6 6
