2. Test Scores
File: test_scores.py
Write pseudocode for the main() part of a program that asks the user to enter 4 test scores between 0 and 100, then displays a JCU grade for each score and also the average test score.
When you have written the pseudocode for main, implement your solution in Python code and test it with a range of meaningful data.
Remember that we've done the JCU grades question before, so copy your function from that practical code file.
Sample Output
Score: 3
Score: 50.5
Score: 66
Score: 100
Score 3.0, which is N
Score 50.5, which is P
Score 66.0, which is C
Score 100.0, which is HD
The average score was 54.875
Enhancements
When you have that working...
We asked for 4 scores. Have a look at your code... did you use 4 as a numeric literal or a constant?Change 4 to 3... Did you have to change the program in more than one place?If so, then you've missed one of the things we've taught...As a strong guideline: if you need to use the same literal more than once, you…
#include <stdio.h>void cubeByReference( int *nPtr ); // function prototypeint main( void ){ int number = 5; // initialize number printf("The original value of number is %d", number ); // pass address of number to cubeByReference cubeByReference( &number ); printf("\nThe new value of number is %d\n", number );} // end main
void cubeByReference( int *nPtr ){ *nPtr = *nPtr* *nPtr* *nPtr;}
passing argument by reference -
We modify the code above
1- define a second argument (example "int number2 = 9") and a pointer to it
2- define a second function (addByReference) that adds number2 to number - passing both arguments by reference
3- print-out the result (that is in number)

Python Functions for Statistical Applications
1A. Implementation with the standard def keyword
Suppose you have done a statistical comparison using the Z-scores approach. Write a function for calculating the lower bound of the 95% CI. A starter code for this function is already provided to you below.
def compute_lower_bound(n, mu, stdev, z=1.96):"""Computes lower bound of a confidence intervalParameters:n: Type int. number of data pointsmu: Type float. sample meanstdev: Type float. sample standard deviationz: Type float. critical value. Default to 95%CI that corresponds to value of 1.96"""# YOUR CODE HERE# Hint: A correct implementation can be as short as just 1 line long!
1B. Using the function of Part 1A
Run your function on the following scenario:
There are 500 data points.
The sample mean is 2525
The sample standard deviation is 7.57.5
The critical value at 95% confidence, ?0.95�0.95, is a constant: 1.96

- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forwardWrite VBA CODE FOR THE FOLLOWING PROBLEM Problem: The Worksheet named Grades contains a place for students to record the grades they have received in their classes. Students put the number of each letter grade received in the B column. (For example, the worksheet currently shows that the student has taken 9 classes and made five As, one B, one C, one D, and one F as grades. You need to write a program that reads the grades from the worksheet and uses a function to calculate the student’s GPA. For this problem you can assume that all classes are worth the same number of credit hours. The function should send back the GPA to the calling procedure. The procedure will then put up a message box that gives the student their GPA and a message about their GPA, all in one message box. The message should be “You qualify for an internship” if the student has a GPA of at least 3.0. It should be “You’re in the danger zone” if the GPA is between 2.0 and 3.0. And it should be “You are on…arrow_forward#include // Function to calculate the factorial of a given positive integer int factorial(int n) { // TODO: Implement the factorial function here } int main() { int num; printf("Enter a positive integer: "); scanf("%d", &num); // TODO: Call the factorial function and print the result } return 0; • Q1: Write a C program to calculate the factorial of a given positive integer entered by the user.arrow_forward

- Create a program using C++ that satisfies the following requirements: SAMPLE ATTACHED Develop a function called "randomPairsGenerator" that generates and displays pairs of random numbers, with a maximum of 5 pairs per line. Within this function, use a loop to create 20 pairs of random numbers:1) The first number in each pair should be within the range of 1 to 50, inclusive.2) The second number in each pair should be within the range of 51 to 100, inclusive. For each pair, print the two numbers side by side, separated by a space. Separate each pair with a comma. After every 5 pairs, start a new line. After all 20 pairs have been generated, display the total count of pairs in which the sum of the two numbers is divisible by 7.arrow_forwardPart3: Exercises Exercise 1: Write a Python program that inputs five positive integer numbers, finds their maximum and sort them in ascending order.

- Lab Assignment For this week's lab assignment, you will write a program called lab9.c. You will write a program so that it contains two functions, one for each conversion. The program will work the same way and will produce the same exact output. The two prototypes should be the following: int btod (int size, char inputBin[size]); int dtob (int input Dec); The algorithm for the main () function should be the following: 1. Declare needed variables 2. Prompt user to enter a binary number 3. Use scanf () to get that value 4. If getting it as a string, use strlen() to find the length of the string 5. Call btod () function sending to it the size and the value that was entered by the user and save the return value so the result can be printed out 2 6. Prompt user to enter a decimal number 7. Use scanf () to get that value 8. Call dtob () function saving the return value in a variable so the result can be printed outarrow_forwardGiven the variable initializations int a[5] = {0, 10, 20, 30, 40};int k = 3;int *p = a + 1;determine the output from each of the following statements:A) cout << a[k];B) cout << *(a + k);C) cout << *a;D) cout << a[*a];E) cout << a[*a + 2];F) cout << *p;G) cout << p[0];H) cout << p[1];arrow_forwardFill in the c code for the question below: Define the function: void deleteAtV1(int num[], int *count , int pos); //The function deletes the item at pos For example: Test Result int num[10]={4,5,1,2,8}; int coun=5; deleteAtV1(num,&count,2); display(num,count); 4528 code: void display(int num[], int size){ int i; for(i=0;i<size; i++) printf("%d", num[i]);} // Fill up this missing code to delete [2} in the arrayarrow_forward
