Write a function that accepts an int array and the array's size as arguments. the function should create a new array that is one element larger than the argument array. the first element of the new array should be set to 0. element 0 of the argument arrayshould be copied to element 1 of the new array, element 1 of the argument array should be copied to element 2 of the new array, and so forth. the function should return a pointer to the new array. demonstrate the function by using it in a main program that reads an integer n (that is not more than 50) from standard input and then reads n integers from a file named data into an array. the program then passes the array to your element shifter function, and prints the values of the new expanded and shifted array on standard output, one value per line. you may assume that the file data has at least n values.

When creating a budget, log fixed expenses before income. after income. after savings. at the top.

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e. g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.

For positive constants a and b, the force between two atoms in a molecule is given f(r) = −a r2 + b r3 , where r > 0 is the distance between the atoms. note: a and b are upper case letters. (a) find f '(r) = (b) find the critical point for f(r). r = (c) find f ''(r) = (d) find the value of r so that f ''(r) = 0.
