Which loop is most commonly used to traverse every element of a fixed-size C++ array using its index?

Options

A. for loop

Answer: (A) for loop

A for loop is commonly used to traverse an array because the array indexes follow a predictable sequence.

For example:

int a[5] = {1, 2, 3, 4, 5};

for(int i = 0; i < 5; i++)
{
cout << a[i];
}

The loop accesses indexes from 0 through 4.
