Question

The following code accomplishes which of the tasks written below? Assume list is an int array that stores positive int values only. int foo = 0; for (int j =0 ; j < list.length; j++) if (list[j] > foo) foo = list[j];

Answer 1

Answer:

It stores the largest value in list (the maximum) in the variable 'foo'.

Explanation:

Following are the description of the answer:

In the above code, they set and initialize the integer data type variable that is 'foo' to 0. Then, they set the for loop that iterates from 0 and end at length of the list. Then, they check the condition, if the list of j i.e., list[j] is greater than the variable 'foo', then the value of the list[j] stored in the variable 'foo'.

So, if the value of the list[j] is greater than 0, then the value of the list[j] is initialized in the variable 'foo'. That's why it stores the largest value.
