Question

1. What is the output of each of the following code segments if the inputs are as follows:

5 0 15 -5 2

Scanner input = new

Scanner(System.in);

int sum = 0;

for(int i = 0; i < 5; i++){

System.out.print(

“Enter a number”);

int number = input.nextInt();

if(number <= 0)

break;

sum += number;

}

System.out.println(sum);

Second Segment:

Scanner input = new

Scanner(System.in);

int sum = 0;

for(int i = 0; i < 5; i++){

System.out.print(

“Enter a number”);

int number = input.nextInt();

if(number <= 0)

continue;

sum += number;

}

System.out.println(sum);

Answer 1

1)  5
Explanation:
-------------
calculates the sum of the numbers until a non-positive number is seen
5 0 15 -5 2
so, after 0 is entered, program stops and prints sum calculated.
that's why answer is 5

2)  22
Explanation:
-------------
calculates the sum of all positive numbers entered
5 0 15 -5 2
=>  5 + 15 + 2
=>  22
that's why answer is 22
