Question

Assume the declarations: double x[8] = {3.0, 2.0, 8.0, 2.5, -1.0, 5.0, 2.0, 7.0}; int i=4; // initialized Suppose that each of the boldfaced, lettered statements is executed in turn, so that each subsequent statement continues the processing of the preceding statement. Describe what each statement does to the array by showing the contents of the array x after each statement is executed. Write your answers on this sheet and hand it in with your programs. *[5] — x[5] — x[6] — x[7] (A) x[i] = 4.0; x[@] — x[1] — x[2] — *[3] — x[4] — B) x[i] = x[i] + 5.0; x[@] – x[1] — x[2] — x[3] — *[4] (©) x[i-1] = x[2*i-3]; x[0] — x[1] — x[2] — x[3] — x[4] — D) x[i+1] = x[2*i-2] + x[2*i-1]; x[@] _ x[1] _ X[2] _ x[3] = x[4] _ E) for (i=3; i < 5; i++) x[i] = x[i+1]; x[0] — x[1] _ x[2] – x[3] _ x[4] _ F) for (i=3; i >= 0; i--) x[i+1] = x[i]; x[0] — x[1] _ x[2] _ x3] _ x[4] _ x[5] — x[6] _ x[7] — x[5] _ x[6] - x[7] x5] — x[6] _ x[7] _

How would I solve this ???

Answer 1

Initial array:
3_2_8_2.5_-1_5_2_7
(A) i is 4, so x[4] is assigned new value 4
3_2_8_2.5_4_5_2_7
(B) i is 4, so x[4] is assigned x[4]+5, x[4] = 4+5
3_2_8_2.5_9_5_2_7
(C) i-1 is 3 and 2*i-3 is 5, so x[3] = x[5]
3_2_8_5_9_5_2_7
(D) i is 4. x[5]=x[6]+x[7]
3_2_8_5_9_9_2_7
(E) i takes values: 3 4 5
3_2_8_9_9_2_2_7
(F) i takes values: 3 2 1 0
3_3_2_8_9_2_2_7

Answer: 3_3_2_8_9_2_2_7
