1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.
Which of the following are true? O The C-library has many functions that are useful in manipulating strings. V If a and b are two different C-string variables, the value in a can be assigned the value in b with the following C-statement: a = b; %3D O The length of the char array holding the string must be at least one character longer than the string itself. O An array identifier cannot be used as a pointer. V The identifier, name, of a C-string is also a pointer to a char data type. The ending character in a C-string must be the newline character, '\n'. O The name of a 1-D array is a pointer to the data type of the array, while the name of a 2-D array is a pointer to a 1-D array of the data type.

use c++ Programming language Write a program that creates a two dimensional array initialized with test data. Use any data type you wish . The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument.

WRITE C++ PROGRAM Looping and Array Monthly Household Excenses - Create arrays (maximum size 15) that will hold the following information: category and amount. Allow the user to enter the category (ex. Water bil) and the corresponding amount spent on it every month. After the data entry, display the household categories and its corresponding amount in descending order (highest amount first) and the total amount spent in a month. Please validate the data: categories must not be blank and amount should not be less than 0. Entries may be less than 15 but not less than 0.

Input the grades of a student by taking marks in 3 different subjects using arrays. Use functions to Design a grade calculator based on following criteria: If the student scores 60 above in all three subjects, then he should get an A grade. If the student scores 60 above in only one subject, he gets a B grade. If he scores 60 below in all subjects he scores C grade
Game of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…
surve in your ive been made available. Each contains data for one household. A single record includes an integer identification number, the annual income for the household, and the number of members of the household. You may assume that no more than 25 households were surveyed. Write a program to store the survey results into an array of user-defined structures of type household. The program should input the survey results from the user._The program should also perform the following operations: (Your program must provide a function for each of the following operations) • Calculate the average household income, and list the identification number and income of each household whose income exceeds the average. • Calculate the percentage of households having incomes below the poverty level. The poverty level, P, may be computed using the formula P = 2000 + 1000 • (m – 2) where m is the number of members in the household. Sample Input 24 5000 4 36 10000 5 45 2000 4 50 4000 2 55 6000 4
