Question

Write a script that will generate seven random integers in the range [-100:200] inclusive and then print the value of each integer and whether it is positive or negative and whether it is even or odd.

An output from this program might be:

-57 is negative and odd.

26 is positive and even.

If zero is one of the random integers generated, remember that zero is even and neither negative or positive.

Hint: even numbers are divisible by 2 with no remainder.

Solve it in MATLAB

Answer #1

**Answer**

Here is your answer, if you have any
doubt please comment, i am here to help you. Here is the matlab
code for finding the above problem. Here we can use
**randi()** built in method for creating the random
numbers. And we can use **mod()** to find the
reminder. So here is the code

```
%creating 7 random numbers including -100 and 200 , which 1x7 vector.
%we can use randi() method to generate random numbers
%Uniformly distributed pseudorandom integers
r = randi([-100,200],1,7);
%iterate through each values in r and check weather it is +ve or -ve and
%even or odd
for i=1:numel(r)
if r(i) <0
%use modulo operator to find the reminder
if mod(r(i),2)==0
fprintf(" %d is negative and even\n ",r(i));
else
fprintf(" %d is negative and odd\n ",r(i));
end
elseif r(i) > 0
if mod(r(i),2)==0
fprintf(" %d is postive and even\n ",r(i));
else
fprintf(" %d is positive and odd\n ",r(i));
end
else
fprintf("zero is even and neither negative or positive");
end
end
```

**output**

i put comment in the code, any doubt please comment

Thanks in advance

***Python
Hailstones, also known as the Collatz
sequence, are a mathematical curiosity. For any number in the
sequence, the next number in the sequence is determined by two
simple rules:
If the current number n is odd, the next number in the
sequence is equal to 3 * n + 1
If the current number n is even instead, the next
number in the sequence is equal to one half of n (i.e.,
n divided by 2)

JAVA Exercise_Pick a Card
Write a program that simulates the action of picking of a card
from a deck of 52 cards. Your program will display the rank and
suit of the card, such as “King of Diamonds” or “Ten of Clubs”.
You will need:
• To generate a random number between 0 and 51
• To define two String variables:
a. The first String should be defined for the card Suit
(“Spades”, “Hearts”, “Diamonds”, “Clubs”)
b. The second String...
