In your question whereas there is a class named window and it would be like this:

class window {
//code here
}

Next is there is a function called close and freeresource and it goes like this:

class window{
function close( ){
//code here
}
function freeresource( ){
// code here
}
public destruct (){
this.close();
this.freeresource();

forsale [732]

Answer:

87 66 55

Explanation:

Array is used o store the multiple values with same data type.

the array show a decimal value .66, i assume this is enter by mistake because option has no decimal value.

The index of the array is start from zero, it means the first element store in the array at position zero.

In the for loop the variable 'i' start from 1 not zero and it goes to i<4 means i=3.

So, it access the element from 2 to 4 because the index is position of element less than 1.

Therefore, 87 66 55 print.
