Write a program application that inputs a sentence from the user (assume no punctuation), then determines and displays the nonduplicate words in alphabetical order. Treat uppercase and lowercase letters the same. Hint: You can use string method Split with no arguments, as in sentence. Split0, to break a sentence into an array of strings containing the individual words. By default, Split uses spaces as delimiters. Use string method ToLower in the select and orderby clauses of your LINQ query to obtain the lowercase version of each word.

Write a loop that prints each country's population in country_pop. sample output for the given program with input 'china: 1365830000,india: 1247220000,united states: 318463000,indonesia: 252164800': united states has 318463000 people. india has 1247220000 people. indonesia has 252164800 people. china has 1365830000 people.

Why would a programmer use the logical operator and in an if statement? a: when an action is to be taken that requires both conditions to be falseb: when an action is to be taken that requires both conditions to be truec: when an action is to be taken that requires the first condition to be falsed: when an action is to be taken that requires the second condition to be truei took the test and the answer is b.

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
