For the questions below, assume an int array, candy, stores the number of candy bars sold by a group of children where candy[j] is the number of candy bars sold by child j. Assume there are 12 children in all. What does the following code do? Scanner scan = Scanner.create(System.in); int value1 = scan.nextInt( ); int value2 = scan.nextInt( ); bars[value1] += value2; 1. adds value1 to the number of bars sold by child value2 2. adds 1 to the number of bars sold by child value1 and child value2 3. adds 1 to the number of bars sold by child value1 4. inputs a new value for the number of bars sold by both child value1 and child value2 5. adds value2 to the number of bars sold by child value1

Solution

Answer: 5. adds value2 to the number of bars sold by child value1

Explanation:

According to the question  candy[j] is the number of candy bars sold by child j

hence bars[value1]=number of candy bars sold by child value1

bars[value1]+=value2 is nothing but bars[value1]=bars[value1]+value2

hence now bars[value1]=old value of bars[value1] + value2

hence ,this adds value2 to the number of bars sold by child value1
