5. (2 points) What are the values in array x after the following code executes (list all of the elements of the array)? CS1113 Introduction to Computer Science Page 2 of 2 double []x 2,-3,4,-5,6,-7 for(int i-1; i < x.length; ++i)

Answer 1

X contains the following elements after the execution of the code:

x={2.0 , -1.0 , 3.0 , -2.0 , 4.0 , -3.0}

As the length of the array is 6

Loop will execute less then 6 that is i value will execute till 5: i<x.length: i<6

Explanation: Every element the array depends on this step x[i]=x[i-1]+x[i]

x[0]=2.0

For value of i=1

x[1] = x[1-1] + x[1] ;

x[1] = 2.0 + -3.0

x[1] = -1.0

********************************

For value of i=2

x[2] = x[2-1] + x[2] ;

x[2] = -1.0 + 4.0

x[2] = 3.0

*******************************

For value of i=3

x[3] = x[3-1] + x[3] ;

x[3] = 3.0+ -5.0

x[3] = -2.0

******************************

For value of i=4

x[4] = x[4-1] + x[4] ;

x[4] = -2.0 + 6.0

x[4] = 4.0

*****************************

For value of i=5

x[5] = x[5-1] + x[5] ;

x[5] = 4.0 + -7.0

x[5] = -3.0
