I am unsure as to why I cannot solve my Computer Science question I was just wondering if someone could show me exactly what they would do the code is in C++:

write a program that display the following manual for user to chose among calculations

Please select one of the following:

  1. addition
  2. subtraction
  3. multiplication
  4. division
  5. exit

The program will then read in the user entry.

when the user chose "1", it will ask the user "Please enter two numbers separated by space:", read these two numbers into variables, add them and display the sum; when the user chose "2", it will ask the user "Please enter two numbers separated by space:", read these two numbers into variables, subtract the 2nd number from the first one and display the result; when the user chose "3", it will ask the user "Please enter two numbers separated by space:", read these two numbers into variables, multiply them and display the product; when the user chose "4", it will ask the user "Please enter two numbers separated by space:", read these two numbers into variables, divide the first number by the 2nd number, and display the quotient; when the user chose "5", exit the program; when what the user entered is not within the range of 1~5, display "This is Not a valid choice."

Write a C++ program to generate two random numbers (Rnd1 and Rnd2). These two numbers should be within a range [100, 500]. If Rnd1 greater than or equals to Rnd2, print out the result of (Rnd1-Rnd2). Otherwise, print out the result of (Rnd2-Rnd1). In all cases, print Rnd1, Rnd2, and the results of subtractions in suitable messages.

Problem Title : Museum Heist

Jojo loves art. In his free time, he usually goes to the museum and admires the artwork there. since Jojo loves are so much, he is planning a heist at the museum. Jojo knows the price of every piece of art and doesn't want to raise suspicion, so he decided to steal the second most expensive art piece. It is guaranteed that there are at least two art pieces with different prices.

Format Input

A line with integer N followed by another line of N numbers denoting the value of Ai.

Format Output

A single line of integer denoting the price of the second most expensive art piece.

Constraints

1. Create a PHP page with standard HTML tags. Remember to save the file with
the .php extension.
Inside the <body> tag, create a PHP section that will show the text "Hello
World!"
2. For this exercise, echo the phrase "Twinkle, Twinkle little star." Create
two variables, one for the word "Twinkle" and one for the word "star". Echo
the statement tothe browser.
3. PHP includes all the standard arithmetic operators. For this PHP
exercise, you will use them along with variables to print equations to the
browser. In your script, create the following variables:
$x=10;
$y=7;
Write code to print out the following:
10 + 7 = 17
10 - 7 = 3
10 * 7 = 70
10 / 7 = 1.4285714285714
10 % 7 = 3
Use numbers only in the above variable assignments, not in the echo
statements. You will need a third variable as well.
Note: this is intended as a simple, beginning exercise, not using arrays or
loops.
4. Arithmetic-assignment operators perform an arithmetic operation on the
variable at the same time as assigning a new value. For this PHP exercise,
write a script to reproduce the output below. Manipulate only one variable
using no simple arithmetic operators to produce the values given in the
statements.
Hint: In the script each statement ends with "Value is now $variable."
Value is now 8.
Add 2. Value is now 10.
Subtract 4. Value is now 6.
Multiply by 5. Value is now 30.
Divide by 3. Value is now 10.
Increment value by one. Value is now 11.
Decrement value by one. Value is now 10.

For your analysis of this module's material, think about the growing capabilities of technology to connect people and the potential opportunities and challenges of the increasing connectivity throughout the world. What is your outlook on the importance of the Internet, IoT (the Internet of Things) and other connectivity technology? Do you agree with Gilder's concept of the "Telecosm" (see module Overview)? In your discussion share an example of at least one benefit and one challenge (that weren't already covered in the module) of the continued development of global connectivity.

1. Write a function named ”ThreeDicesAdd” to perform the following ”experiment” 1000 times: roll 3
six-sided dice and add their values. Put the outcomes in a list called addDiceList. So addDiceList should
have length 1000, and each of the 1000 elements should be an integer from 3 to 18. Plot the histogram of
the outcomes.
2. For the same experiment as in question 1, write a function named ”ThreeDicesAdd2” to increase the
experiment times (N) and see how the histogram of the outcomes changes. For each N, you will have one
histogram plot. Output all plots as a GIF file. (Choose N= 1000 : 10,000 : 1,000,000). matlab question

The following code must be written in Matlab

I want to print the following in Matlab (x1,x2, x3) = (0.33333, 0.33333, 0.33333)  . The whole thing should be on the same line.

I need to use fprintf and write out the coordinates with 5 decimal places of variable x = (0.33333, 0.33333, 0.33333)

Thanks!
