Problem Description: Write a single C++ program that will print results according to the output below. There are 2 subtasks to print, all should be printed on a single program.
Subtask 1: This program is about using for loops. It asks the user for a number n and prints Fibonacci series with first n numbers. First two terms of the Fibonacci series are 1 and all the following terms are sum of its previous two terms. Please use a for loop to calculate the series. Please see the sample output.
Subtask 2: This program is about using arrays and using arrays as a parameter of function. It asks the user for a number sz (length of the array).
Write a program that implement the following function:
array_populate(int num[ ], int sz): This function populates the array num of size sz with random numbers. The numbers should be randomly generated from -99 to 99.
show_array(int num[ ], int sz): This function shows the values of the num array of size sz in a single line.
sum_of_positive(int num[ ], int sz): This function returns the sum of all positive values of the array num.
sum_of_negative(int num[ ], int sz): This function returns the sum of all negative values of the array num.
sum_of_even(int num[ ], int sz): This function returns the sum of all even values of the array num.
sum_of_odd(int num[ ], int sz): This function returns the sum of all odd values of the array num. Please see the sample output
Answers
The given problem requires writing a C++ program that consists of two subtasks. Subtask 1 involves using a for loop to print the Fibonacci series up to a given number.
Subtask 2 involves implementing functions to populate an array with random numbers, display the array, and calculate the sums of positive, negative, even, and odd numbers in the array.
To solve the problem, you can follow these steps:
Subtask 1:
1. Ask the user to input a number, let's call it `n`.
2. Declare variables `a`, `b`, and `c` and initialize `a` and `b` as 1.
3. Print `a` and `b` as the first two numbers of the Fibonacci series.
4. Use a for loop to iterate `i` from 3 to `n`.
5. In each iteration, calculate the next Fibonacci number `c` by adding the previous two numbers (`a` and `b`).
6. Update the values of `a` and `b` by shifting them to the right (`a = b` and `b = c`).
7. Print `c` as the next number in the Fibonacci series.
Subtask 2:
1. Ask the user to input the length of the array, `sz`.
2. Declare an integer array `num` of size `sz`.
3. Implement the `array_populate` function that takes the array `num` and `sz` as parameters.
4. Inside the function, use a for loop to iterate over the array elements from 0 to `sz-1`.
5. Generate a random number using the `rand()` function within the range of -99 to 99 and assign it to `num[i]`.
6. Implement the `show_array` function that takes the array `num` and `sz` as parameters.
7. Inside the function, use a for loop to iterate over the array elements from 0 to `sz-1` and print each element.
8. Implement the `sum_of_positive`, `sum_of_negative`, `sum_of_even`, and `sum_of_odd` functions that take the array `num` and `sz` as parameters.
9. Inside each function, use a for loop to iterate over the array elements and calculate the sums based on the respective conditions.
10. Return the calculated sums from the corresponding functions.
11. In the main function, call the `array_populate` function, followed by calling the `show_array` function to display the populated array.
12. Finally, call the remaining functions (`sum_of_positive`, `sum_of_negative`, `sum_of_even`, and `sum_of_odd`) and print their respective results.
By following these steps, you can create a C++ program that satisfies the requirements of both subtasks and produces the expected output.

To search for a word anywhere in a field that contains "night" you would enter _________.
A. ?night?
B. *night*
C. #night#
D. !night!
Answers
To search for a word anywhere in a field that contains "night," you would enter option B: night. This wildcard pattern allows for matching any characters before and after the word "night," Effectively searching for the word in any position within the field.
Wildcard characters are used in search patterns to represent unknown or variable characters. In this scenario, the goal is to search for a word that contains "night" anywhere within a field.
Option B, night, is the correct choice because the asterisk (*) acts as a wildcard character that matches any number of characters (including zero characters) before and after the word "night." This pattern allows for the word "night" to be found in any position within the field, as long as it is preceded or followed by any combination of characters.
The other options (A, C, and D) do not provide the necessary wildcard functionality to match the word "night" anywhere within the field. They either include specific characters (such as question marks or hash symbols) that do not represent wildcards or use exclamation marks that do not have a defined meaning in this context.

What is a camera shutter speed, and what creative things can you do with it?
O Controls Exposure and Motion
O Controls Depth Field and Motion
O Controls Exposure and Depth of field
O Controls ISO and Motion
Answers
A camera shutter speed refers to the length of time that the camera's shutter remains open, allowing light to enter the camera and expose the image sensor. It is measured in fractions of a second, such as 1/500, 1/1000, or 1/2000.
The shutter speed has two main creative effects: exposure and motion control.
Exposure control: By adjusting the shutter speed, you can control the amount of light that reaches the image sensor. A faster shutter speed (e.g., 1/1000) lets in less light, resulting in a darker image. On the other hand, a slower shutter speed (e.g., 1/30) allows more light, creating a brighter image. This adjustment is crucial in different lighting conditions and helps you achieve the desired exposure.
Motion control: Shutter speed also determines how motion is captured in a photograph. A fast shutter speed freezes motion, allowing you to capture sharp images of fast-moving subjects like sports or wildlife. Conversely, a slow shutter speed blurs moving objects, enabling creative effects such as light trails or silky smooth waterfalls.
In summary, the camera shutter speed controls exposure and motion. By adjusting it, you can achieve proper exposure and create various creative effects in your photographs.

write a program to ask 10 numbers and find out total even and odd numbers
Answers
A program in Python that asks the user for 10 numbers and determines the total count of even and odd numbers is given below.
Program:
even_count = 0
odd_count = 0
for i in range(10):
number = int(input("Enter number: "))
if number % 2 == 0: # Check if the number is even
even_count += 1
else:
odd_count += 1
print("Total even numbers:", even_count)
print("Total odd numbers:", odd_count)
In this program, we use a for loop to iterate 10 times, asking the user to enter a number in each iteration.
We then check whether the number is even by using the modulo operator % to check if the remainder of dividing the number by 2 is zero. If it is, we increment the even_count variable; otherwise, we increment the odd_count variable.
After the loop completes, we print the total count of even and odd numbers.
