Generating random numbers

Start by creating a new project, then practice generating different random numbers and display them at the screen:

1. Generate any random integer
2. Generate a random integer between -10 and 10 including these boundary values
3. Generate a random double

Note you only need 1 instance of Random class to generate these numbers.

Execute the program a few times to make sure the outputs are different each time.

Once you have successfully generated the 3 random numbers described above, add the following enhancements to the program:

1. Generate any random integer 5 times
2. Generate a random integer between -10 and 10 including these boundary values, 10 times
3. Generate a random double, 5 times

Execute the program again, a few times, to make sure these values change on each execution.

Manipulating two arrays

This problem combines random number generation with arrays. Using a Random object, write a program that:

1. declares two arrays of int of size 8,

2. initializes the values of the first array with random numbers between 0 and 9,

3. initializes the values of second array with random numbers between 0 and 9,

4. displays the contents of the two arrays in a table, and, for each index, a letter indicating whether the first array “won” or “lost” a contest with the second array:

   • "W" if the value in the first array is greater than the value in the second array
   • "T" if they are equal, and
   • "L" if it is less

An example execution of this program would display:

0       8       L
5       3       W
3       3       T
1       2       L
3       1       W
9       0       W
9       0       W
1       5       L

In this example, the first array contains “0 5 3 1 3 9 9 1” and the second contains “8 3 3 2 1 0 0 5”.

“Higher or Lower” Game

Write a program that:

1. Starts by having computer choose a random number between 0 and 100. Store that number at a variable.

2. Asks the user to enter a numerical value between 0 and 100 and stores the user’s answer in a variable.

3. Add an if statement that displays on the screen "You guessed correctly" if the number entered by the user matches the number selected by computer.

4. Add an if statement that displays on the screen "Too high!" if the number entered by the user is strictly greater than the number selected by computer.

5. Add an if statement that displays on the screen "Too low!" if the number entered by the user is strictly smaller than the number selected by computer.

6. Add an if statement that displays on the screen "You found a multiple !" if the number entered by the user is a multiple of the number selected by computer, but different from it.
   

7. When user enters a number that does not match computers selection, the user should be able to enter another number. This continues until user guesses correctly.
   

8. Keep count of how many guesses it takes for the user to arrive to the correct answer. After user guesses correctly, display that count, for example:

   You guessed correctly.
   That was 7 guesses!

You can adjust your program so that e.g. if the user enters a number that is at the same time higher and a multiple of computer’s number, only one message is displayed.
