Write a program that takes a list of students" names and marks and calculates the average marks. You are required to declare two arrays called names and marks. Assume number of students are 5. Declare array names: (use 2-D array) char names[num_std][name_len]; //name length can be 20 characters long Declare array marks: float marks[num_std]; Sample output: Enter student name: Jason Enter student marks: 60 Enter student name: Ahmad Enter student marks: 77 Enter student name: Chong Enter student marks : 88 Enter student name: Kumar Enter student marks: 70 Enter student name: Daniel Enter student marks : 55 Jason 60.00 Ahmad 77.00 Chong 88.00 Kumar 70.00 Daniel 55.00 Average marks for 5 students : 70.00

Assignment Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen. NOTE: Checking the correctness of a char and correcting it (if necessary) MUST be done in the function with a…
Question 2 Write a program that display the positions of min and max elements in an array. The user should enter the size of the array. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 68 5 is found at position 1 68 is found at position 4
Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9
Payroll Write a program that uses the following arrays: empId: an array of seven long integers to hold employee identification numbers. The array should be initialized with the following numbers: 5658845 4520125 7895122 8777541 8451277 1302850 7580489 hours: an array of seven integers to hold the number of hours worked by each employee payRate: an array of seven doubles to hold each employee's hourly pay rate wages: an array of seven doubles to hold each employee's gross wages The program should relate the data in each array through the subscripts. For example, the number in element 0 of the hours array should be the number of hours worked by the employee whose identification number is stored in element 0 of the empId array. That same employee's pay rate should be stored in element 0 of the payRate array. The program should display each employee number and ask the user to enter that employee's hours and pay rate. It should then calculate the gross wages for that employee (hours times…
NOTE: PYTHON CODE Create a python program that will ask the user to enter ten numbers and get the sum of all odd numbers. The numbers will be stored in array. The array value will be pass as argument to the function. EXAMPLE OUTPUT: Enter 10 numbers: 1 2 3 4 5 6 7 8 9 10 The sum of all odd numbers is 25.
JAVA PROGRAM: Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.
Programming language is "C" : ( write with comments please, The comments is very important): 30 students were asked to rate the quality of the food in the students cafeteriaon a scale of 1 to 10 ( 1 means awful and 10 means excellent) Place the 30 responses in an integer array and summarize the results of the poll. you should put the frequency for the program.1---52---93---110---20
FYI: Please write the code in Pseudocode (no programming language please) 1. Write a pseudocode that outputs the contents of parallel arrays. You do NOT have to write the entire program. The first array will hold phone numbers The second array will hold company names You do NOT need to load the arrays. Your code can assume they are already loaded with data. arrays are named phone[] and company[]
