  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:

Here is the list of problems to choose from:
olya-2409 [2.1K]

Answer:

There's a parking lot that is 600m² big. The lot must be able to hold at least 3 buses and 10 cars.

Each car takes up 6m² and each bus takes up 30m².

However, there can only be 60 vehicles in the lot at any given time.

The cost to park in the lot is $2.50 per day for cars and $7.50 per day for buses. The lot must make at least $75 each day to break even.

What is a possible car to bus ratio that would allow the lot to make profit?

Consider the code fragment below (with nested loops). int sum = 0;for (int i = 1; i < 5; i++) for (int j = 1; j <= i; j++)
sammy [17]

Answer:

Option d is the correct answer for the above question.

Explanation:

  • The first loop of the program has a second loop and then the statement. In this scenario, the second loop executes for the value of the first loop and the statement executes for the value of the second loop.
  • The first loop executes 4 times, Then the second loop or inner loop executes n times for the n iteration of the first loop, for example, 1 time for the first iteration of the first loop, 2 times for the second iteration of the first loop and so on.
  • Then the inner loop executes (1+2+3+4) iteration which gives the result 10 iterations.
  • The sum initial value is 0 and the "sum++", increase the value of the sum by 1.
  • So the value of the sum becomes 10 after completing 10 iterations of the inner for loop.
  • Hence the 10 will be the output. So the Option d is the correct answer while the other is not.
