4. Only (ii)
<u>Explanation:</u>
The declaration of the array can be of two types:
1. int a[100];
2. int[] a = new int[100];
The general thing about an array is that whenever we want to undergo traversal in an array, we always have to start from the 0th position as the size of the array may be a whole number (let us say 10). So, to undergo traversal in an array, we start from 0 to n-1 (in this case 9) such that it covers the size of the array.
The size of an array can be finite or infinite. The general rule is it starts from 0 to n-1 where n is the size of the array. In the above example, the range of the index of the array will be 0 through 100 and not 1 through 100.
The answer is C. Tablet, because that is the quickest, easiest, and most recent way of communication.
Answer:
Answered below
Explanation:
//Program is written in Java programming language
Class RegularPolygon{
int sides = 0;
int length = 0;
}
public void randomize(RegularPolygon polygon){
int randomSides = (int) 10 + (Math.random() * 20);
double randomLength = 5 + (Math.random() * 11);
polygon.sides = randomSides;
polygon.length = randomLength;
}
The answer is B) Template.
Various templates are available in most all desktop publishing programs, from resume templates in Word to Income Statement templates in Excel. Templates are useful for skipping the general "setup" process of making a document, and allow you to focus more on filling the document with the relevant data and polishing it to your specific needs once most of the legwork is done.
