11: series.cpp) Write a program that will add the terms of an infinite geometric series. The program should read the first term (a) and the common ratio (r) for the series. It should then compute the sum in two ways: by formula ( s=, ), and by adding the individual terms until the answer agrees with the formula to 7 significant digits. Then

Problem D: Different Dice Game Consider the following game for two players: The first player rolls a pair of dice of fair six-sided dice. If the two dice show different numbers, the player's score is the larger of the two numbers. Otherwise, the player's score is the sum of the two numbers. At this point, the player is asked if they want to remove their lower die and re-roll one die. If they say no, the player keeps her score and their turn is over. If they say yes, then they roll one more die and the number showing on this die replaces the lower of the original two rolls. Then these two dice rolls are scored accordingly. (For example, if the initial roll was a 2 and 5, if the player doesn't roll again, she gets 5 points. If she does roll again and obtains a 4, her score is still 5. If she rolled again and obtained a 6, her score would be a 6. If she rollwed again and obtained a 5, her score would be a 10.) The second player goes after the first, doing the exact same steps as the first…
3 Write a program to compute the sum of two matrices and then print it. Firstly user will be asked to enter the order of matrix (number of rows and columns) and then two matrices. For example if the user entered order as 2, 2 i.e. two rows and two columns and matrices as First Matrix:- 3 4 Second Matrix:- 4 5 -15 Then output of the program (sum of First and Second matrix) will be 5 7 2 9
5: CheckLetter.cpp) Write a program that adds a check letter to an eight-digit number. The check letter should be computed as follows: Break the number up into 4 two-digit numbers. Add the four numbers together. Find the remainder after division by 26. The check letter is the letter in the alphabet that corresponds to the number just computed. (A=0, B=1, C=2, etc.) Print the original number followed by the check letter. Use at least one function that returns a value when you write this program.

8. Write program to check whether a number is Armstrong or not. [Hint] :A positive integer is called an Armstrong number if the sum of cubes of individual digit is equal to that number itself. For examples: 1. 153 = 1*1*1 + 5*5*5 + 3*3*3 // 153 is an Armstrong number. 2. 12 is not equal to 1*1*1+2*2*2 // 12 is not an Armstrong number.

1. Federal law requires that hourly employees be paid “time-and-a-half” for work in excess of 40 hours in a week.For example, if a person’s hourly wage is $12 and he or she works 60 hours in a week, the person’s gross pay shouldbe (40 *12) + (1.5 *12 * (60-40)) = $840.Write a program that requests the floating number of hours a person works in a given week and the person’s hourlywage as input, and then displays the person’s gross pay. Save it as overtimePay.py

Voltage readings are obtained from an electrical substation once every hour for six hours (so there are sixreadings). Write a program to perform the following checks on the substation:i) display all voltages that differ from the average by more than 10% of the average.ii) display all pairs of consecutive hours where the change from the voltage at one hourto the next is greater than 15% of the average.
