Question

Hello everybody,
I have a big doubts!
How can i take for the following code all the items introduced in the array to be calculated as it described? Why the first value it's not taking into consideration?
Thanks a lot!!
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int length = scanner.nextInt();
int[] sides = new int[length];
for (int i = 0; i < length; i++) {
sides[i] = scanner.nextInt();
}
//your code goes here
int sum;
for(int x:sides) {
sum=x*x;
System.out.println(sum);
}
}
}

Answer 1

because first number is read as the length of the array
int length = scanner.nextInt();

Answer 2

Wt's wrong in this??
It's perfectly alright!! "The o/p is squares of given numbers.." Code is working fine..!! No prob in this.

Answer 3

Yes, but it seems that it squares well, excepts the first given number.
For the example below, it squares the entire indexes within the given arrray.
public class Program {
public static void main(String[] args) {
int[ ] array = {3, 2, 3, 5};
int sqr;
for (int t: array){
sqr=t*t;
System.out.println(sqr);
} }
}
