Write a program to input ten integer numbers into an array named fmax and determine both the maximum value entered and the index number for the maximum. Your program should contain only one loop. After displaying the numbers of the array, display these two messages:

The maximum value is : __

This is element number __ in the list of numbers

Have your program display the correct values in place of the underlines in the messages.

Write a program to input or initialize the following integer numbers into an array called grades: 89,95,72,83,99,54,86,75,92,73,79,75, 82,73,87. Calculate the average of the numbers and use the average to determine the deviation of each value from the average. Store each deviation in an array named deviation. Each deviation is obtained as the element value less the average of all the data. Have your program display each deviation alongside its corresponding element from the grades array.

Calculate the variance of the data. The variance is obtained by squaring each individual deviation and dividing the sum of the squared deviations by the number of deviations.

Write a program that declares three one dimensional arrays named price, quantity, and amount. Each array should be declared in main( ) and should be capable of holding ten double-precision numbers. The numbers that should be stored in price are 10.64, 14.89,15.21,74.21,23.8,61.26,92.37, 12.73, 2.99, 58.98. The numbers should be stored in quantity are 4, 8,17,2,94,61,20,78,55,41. You program should pass these three arrays to a function named extend(), which should calculate the elements in the amount array as the product of the corresponding elements in the price and quantity arrays (for example, amount[1] = price[1] * quantity[1]) . After extend() have put values into the amount array, the array should be display from within main().

- (Lastname_Lab7_p4.cpp)

- Write a function named findmax() that finds and displays the maximum values in a two dimensional array of integers. The array should be declared as a 10 row

by 20 column array of integers in main() and populated with random numbers between 0 and 100.

- Modify the function written above so that it also displays the row and column numbers of the element with the maximum value.

- ( Lastname_Lab7_p5.cpp)

Use a one dimensional array to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, print it only if it is not a duplicate of a number already read. Provide for the “worst case” in which all 20 numbers are different. Use the smallest possible array to solve this problem.

- (Optional. Lastname_Lab7_p6.cpp)

Write a program that simulates the rolling of two dice. The program should use rand to roll the first die, and should use rand again to roll the second die. The sum of the two values should then be calculated. Note: Since each die can show an integer value from 1 to 6, then the sum of the two values will vary from 2 to 12 with 7 being the most frequent sum and 2 and 12 being the least frequent sums. The following figure shows the 36 possible combinations of the two dice. Your program should roll the two dice 36,000 times. Use a one dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals are reasonable, i.e., there are six ways to roll a 7, so approximately one sixth of all the rolls should be 7.
