write a program to read an unknown number of scores (double type) from the keyboard and calculate the sum and average (mean) of the scores. The program will repeatedly read scores until a non-number is entered.The program should then output the sum and the average of all of the numbers to the screen to an accuracy of 2 decimal places. You don't need to use an array to store all of the scores (we haven't learned about arrays yet, but most importantly, it is not necessary). Use variables to store the sum and number of scores you read and calculate the average after the user enters the non-numeric value

(Practice) Write a program to input eight integer numbers in an array named temp. As each number is input, add the numbers to a total. After all numbers are input, display the numbers and their average.
Write a program that prompts the user for an integer, then asks user to enter that many integer value. Store these values in an integer array and print the array. Reverse the array elements so that first element become the last element, the second element become the second to last element, and so on, with the old last element now first. Do not just reverse the order in which they are printed; actually, change the way they are stored in the array. Try not to create a second array; just rearrange the elements within the array you have. (Hints; Swap elements that need to change place.) When the elements have been reversed, Print the array again.
Write a program that creates an integer array of size 10 and fills the array with valuesset by the programmer (not entered by the user). Then, the program will remove all theprime numbers from the original array and store them in a new array. Note that afterthe program finishes execution, the original array should not contain any prime number.
Write a program that creates a two dimensional array with 4 rows and 3 columns that contains the below numbers. Let the computer prompt you to enter these numbers. 8 6 1 7 3 0 2 5 9 5 6 7 After that, calculate and print the total and average of these values.
Write a program to enter 10 numbers using keyboard and put them in an array. Now generate another array of same size from the array created in the first step by satisfying the following conditions:  If the number is prime then write ‘P’ to the same location of the second array  If the number is divisible by 5 then write ‘F’  If the number is divisible by 3 then write ‘T’  If number is an Even number and neither divisible by 3 or 5 then write ‘E’  If number is an Odd number and a non-prime number write ‘N’ Consider the following example: A = 12 11 19 49 27 30 35 39 7 61 B = T P P N T F F T P P
In Python: Write a program that reads two sets of exam scores of five students from user input and stores the scores into two NumPy arrays (exam1 and exam2). The program then calculates the average of the two exams for each of the five students and outputs the average scores as a NumPy array. The program finally counts the number of average scores that are 80 or higher and outputs the count. Ex: If the input of the two sets of scores are: 75 80 65 82 92 88 85 75 95 73 where [75 80 65 82 92] is stored in NumPy array exam1, and [88 85 75 95 73] is stored in NumPy array exam2. The program then outputs: Average scores: [81.5 82.5 70. 88.5 82.5] Number of students who received 80 and above: 4
Write a program that prints at least 10 characters of your name (last, first) in uppercase at the terminal. Use a n by m array (i.e., a two dimensional array, with n (=7) as size of the first dimension and m (=10) as the second dimension) to represent each oversize letter. C++, the name is "Krish"
Write a program to enter 10 numbers using keyboard and put them in an array.Now generate another array of same size from the array created in the first stepby satisfying the following conditions: If the number is prime then write ‘P’ to the same location of the secondarray If the number is divisible by 5 then write ‘F’ If the number is divisible by 3 then write ‘T’ If number is an Even number and neither divisible by 3 or 5 then write‘E’ If number is an Odd number and a non-prime number write ‘N’
Write a program that prompts the user to enter 50 integers and stores them in an array. The program then determines and outputs which numbers in the array are sum of two other array elements. If an array element is the sum of two other array elements, then for this array element, the program should output all such pairs separated by a ';'.
Write a program that allows a user to enter any desired amount of student grades, stores the grades in an array, then prints the results to the screen. Then, find the average of the grades.
Write a program to read a list of exam scores given as integer percentages in the range 0 to 100 and store them into an array. Make sure to validate the scores are within range. Display the total number of grades, and the number of each letter-grade using the following grading scale: 90 to 100 is an A 80 to 89 is a B 70 to 79 is a C 60 to 69 is a D 0 to 59 is an F Use a negative score as a sentinel value to indicate the end of the input. (The negative value is used only to end the loop, so do not use it in the calculations.) For example, if the input is 98 87 86 85 85 78 73 72 72 72 70 66 63 50 −1 the output would be: Total number of grades = 14 Number of A’s = 1 Number of B’s = 4 Number of C’s = 6 Number of D’s = 2 Number of F’s = 1
Write a program that creates an array of integers sine 10. And do the following- a) Ask the user to enter 10 numbers (all > O) one by one and store them in the array. If user enters a number «0 then program should ask user to enter the number again with a message that "Pl enter a number >0" b) Print the smallest number c) Print the largest number d) Print the average
