Answer from AI
In most programming languages, the first element of an array is accessed by index 0. For example, if there is an array arr, then the first element will be arr[0].
Example in JavaScript:
const arr = [10, 20, 30];
console.log(arr[0]); // Outputs 10
This rule applies in languages such as C, C++, Java, JavaScript, Python (lists), Go, and many others.
