What the reason for getting the error in it??

Question

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner a = new Scanner(System.in);
int x = 0;
int b = a.nextInt();
for(int i=0;i<=b;i++) {
int c = a.nextInt();
if(c%2==0) {
x = x+c;

}
System.out.println(x);

}

}
}

There should be i < b instead of i <= b because index start from 0 so if you do <= then you have take one extra input.

For example if you takes b = 4 then your other input should be 5 like 1, 3, 5, 6, 7

Answer 2

This code works. In SL Playground you have to set all input data at the start, for example an input can be:

2
1
2
3

Answer 3

Thanks!

Also print statement should be outside loop if you want to get sum of all even number.

int x = 0;

//b input

for (int i = 0; i < b; i++) {
//c input

if (c % 2 == 0)
x = x + c;
}

System.out.print(x);
