Write a program that creates a 4 x 5 array called numbers. The elements in your array should all be random numbers between -30 and 30, inclusive. Then, print the array as a grid.
For instance, the 2 x 2 array [[1,2],[3,4]] as a grid could be printed as:
1 2
3 4
Sample Output
18 -18 10 0 -7
-20 0 17 29 -26
14 20 27 4 19
-14 12 -29 25 28
Note: the numbers generated in your program will not match the sample output, as they will be randomly generated.

Intro to Computer Science:
A zero-tolerance policy means that if the employee violates the policy, they will be _____.
promoted
fired
warned
reprimanded
The correct answer is: fired :)
A zero-tolerance policy means that if the employee violates the policy, they will be fired. Thus, the correct answer is option B.
What is a Zero-tolerance policy?A zero tolerance policy is one that penalizes every violation of a stated rule. People in positions of authority are prohibited by zero tolerance policies from exercising discretion or changing punishments to fit the circumstances subjectively. They must impose a predetermined punishment regardless of individual guilt, extenuating circumstances, or history.
Zero tolerance policies are studied in criminology and are used in both formal and informal policing systems worldwide. If an employee violates the policy, there will be no tolerance and they will be fired.
Therefore, a zero-tolerance policy means that if the employee violates the policy, they will be fired.

In the 1760s and early 1770s, the British government wanted to raise money by taxing the residents of its colonies in North America. They taxed goods such as sugar and tea and even placed a tax on the printing of documents. These actions angered the colonists, who thought that taxation was unfair since they had no representation in the British government. For this reason, a group of colonists dumped hundreds of chests of tea from Britain into Boston Harbor in 1773, in what became known as the Boston Tea Party. As a result, England passed a series of harsh new laws to punish the colonists, further angering them. The Continental Congress met to voice the colonists' grievances, and eventually, on July 4, 1776, the colonists declared their independence from Britain.
Answer:
Taxes and other laws imposed on the colonies led the colonists to declare independence from England.
Explanation:
During the British government, laws taxes, and other laws increased in the colonies which led the colonists to declare independence from England.
How colonists declared their independence from Britain?As a result, the British were forced to deploy a large army in North America on March 22, 1765, the British parliament passed the Stamp Act.
Which aimed to raise money by levying a tax on all legal and official papers and publications that were being distributed across the colonies. The Stamp Act angered the American colonists, which moved fast to oppose it.
A direct appeal to Parliament was virtually difficult due to the colony's extreme distance from London, the heart of British politics.
Therefore to raise money and increase taxes and laws colonists declared their independence on 4 July 1776 from Britain.

Write a function named count_vowels that accepts two arguments: a string and an empty dictionary. The function should count the number of times each vowel (the letters a, e, i, o, and u) appears in the string, and use the dictionary to store those counts. When the function ends, the dictionary should have exactly 5 elements. In each element, the key will be a vowel (lowercase) and the value will be the number of times the vowel appears in the string. For example, if the string argument is 'Now is the time', the function will store the following elements in the dictionary: 'a': 0 • 'e': 2 'i': 2 'o': 1 'u': 0 The function should not return a value.
The function that counts the number of times a vowel exist in a string is as follows:

9.12: Element Shifter
Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is one element larger than the argument array. The first element of the new array should be set to 0. Element 0 of the argument array should be copied to element 1 of the new array, element 1 of the argument array should be copied to element 2 of the new array, and so forth. The function should return a pointer to the new array. Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array. The program then passes the array to your element shifter function, and prints the values of the new expanded and shifted array on standard output, one value per line. You may assume that the file data has at least N values.
Prompts And Output Labels. There are no prompts for the integer and no labels for the reversed array that is printed out.
Input Validation. If the integer read in from standard input exceeds 50 or is less than 0 the program terminates silently.
