mean 

given a list of integers,write a program to print the mean

mean - the average value of all the numbers.

input 

the input will be a single line of containing space-separated integers.

output

the first line of output should contain the mean, round off the value to 2 decimal places.

mean should always be a float value.

mean should be a float value when there are even number of elements, otherwise should be an integer value.

see sample input/output for the output format

explanation 

for example, if the given list of integers are 

2 4 5 6 7 8 2 4 5 2 3 8

the average of all the numbers is 4.67.

after sorting the array,

2 2 2 3 4 4 5 6 7 8 8

Delete btn is clicked

The blog element &the respective btn shouldbe deleted.

fill script code:

let blgList = [{

    blgName:"TechCrunch",

    uniqueNo:1,

  },

  {

    blgName:"Wired",

    uniqueNo:2,

  }

];

let blgsListContainer = document.getElementById("blogsListContainer");

function createAndAppendItem(blg) {

  let blgId = "blog" + blg.uniqueNo;

  let btnId = "button" + blg.uniqueNo;

let blgEl = document.createElement("li");

  blgEl.id = blgId;

  blgEl.textContent = blg.blgName;

  blgsListContainer.appendChild(blgEl);

let btnEl = document.createElement("button");

  btnEl.classList.add("btn", "btn-danger", "ml-3");

  btnEl.textContent ="Delete";

  btnEl.id = buttonId;

 // Write your code here

 blgEl.appendChild(btnEl);

}

for (let blg of blgList) {

  createAndAppendItem(blg);

}

1. Create (4) java classes. Name them RunEmployee, Employee, FullTimeEmployee, PartTimeEmployee. The Runemployee class shall contain the main method and will be used to execute the program.
2. Write a simple payroll program that will display employee's information. Refer to the UML Class Diagram for the names of the variable and method. This should be the sequence of the program upon execution:

• Ask the user to input the name of the employee
• Prompt the user to select between full time and part time by pressing either F (full time) or P (part time).
• If F is press, ask the user to type his monthly salary. Then, display his name and monthly salary.

If P is pressed, ask the user to type his rate (pay) per hour and the number of hours he worked for the entire month separated by a space. Then, display his name and wage.

1. Create a project named LabExer2
2. Construct a simple purchasing program based on the UML Class Diagram below.

• itemName: String
• itemPrice: double
• itemQuantity: int
• amountDue: double

• setItemName(StringnewitemName): void
• setTotalCost(int quantity, double price): void
• getItemName(): String
• getTotalCost(): double
• readInput(): void
• writeOutput(): void

storing the input to the next variable name based on data type

For String s.nextLine()

For int s.nextInt()

For double: s.nextDouble()

Write a C++ program that prompts a user for three integers- the first denoting a month (1 to 12), the second denoting a day (1 to 31) and the third denoting a year. The output is displayed as "month day, year" string where month represents the name of the month.

For example, if inputs are 12, 15 and 2020 respectively, the output is December 15,

Write a program in C++ that reads text from the keyboard and stores it in a file named “File1.txt”. Also, for each of the specified prototypes given below, write the function definitions.

 void copyselc(ifstream& fp, ofstream& fp1):This function reads the contents of the file “File1.txt” and copies those lines from the file that begin with the character „#‟ to the file named “File2.txt”.

 void checksize(ifstream& fp1,ifstream& fp2):This function reads two files “File1.txt” and “File2.txt” and counts the number of characters in both the files. If the count of characters in both the files is same, then the function should print the message “Both Files are of the same size” else it should display “Size of the files is not same”.

 void dispNumNames(ifstream& fp):Assuming that the file “File2.txt” may also contain numbers (1 to 5), this function will read the contents from the file and display the number names for any numbers encountered. 

Write a program in C++ that defines a class named StringOps. Declare data members of

this class as described below:

 variable str of data type string.

 variable size of data type integer which represents the length of the string str.
