C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.

D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.

answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )

  9.        break;
  10.    case 1:
  11.        console.log("Feb " + dateComp[0] + "," + dateComp[2])
  12.        break;
  13.    case 2:
  14.        console.log("Mar " + dateComp[0] + "," + dateComp[2])
  15.        break;
  16.    case 3:
  17.        console.log("Apr " + dateComp[0] + "," + dateComp[2])
  18.        break;
  19.    case 4:
  20.        console.log("May " + dateComp[0] + "," + dateComp[2])
  21.        break;
  22.    case 5:
  23.        console.log("Jun " + dateComp[0] + "," + dateComp[2])
  24.        break;
  25.    case 6:
  26.        console.log("Jul " + dateComp[0] + "," + dateComp[2])
  27.        break;
  28.    case 7:
  29.        console.log("Aug " + dateComp[0] + "," + dateComp[2])
  30.        break;
  31.    case 8:
  32.        console.log("Sept " + dateComp[0] + "," + dateComp[2])
  33.        break;
  34.    case 9:
  35.        console.log("Oct " + dateComp[0] + "," + dateComp[2])
  36.        break;
  37.    case 10:

  39.        break;
  40.    case 11:
  41.        console.log("Dec " + dateComp[0] + "," + dateComp[2])
  42.        break;
  43. }

Explanation:

The solution code is written in JavaScript.

Firstly, create a Date object (Line 1). The date object will automatically capture the current date and time.

Next create an array dateComp to hold the day, month and year (Line 3 -5). We use the getDate method to get current day, getMonth method for current month and getFullYear method for current year.

This is important to note that the getMonth method will return the value range from 0 - 11 with the Jan is represented as 0, Feb is 1 and so forth. Presume we intend to display the date using the format "month day, year", we can create a switch structure to check the month value which is range from 0 to 11. If month value is 0, generate string Jan + current day + "," + current year. We generate the date string based on different switch cases (7 - 44). We shall see the output similar to the date string as shown below:
