of pairs of numbers as follows 1 Product number 2 Quantity sold for one day Your program should use a switch statement to help determine the retail price for each product and should use a sentinel controlled loop to calculate the total retail value of all products sold in a given week 7days ExerciseExercise 5 5 forfor andand dodo whilewhile repetitionrepetition statementsstatements 精品文档 4欢迎下载 1 Write a program which uses a do while loop to print out the first 10 powers of 2 other than 0 ie it prints out the values of 21 22 210 Use a for loop to do the same 2 The constant can be calculated by the infinite series 4 4 4 34 3 4 54 5 4 74 7 4 94 9 4 114 11 Write a C program that uses a do while loop to calculate using the series The program should ask the user how many terms in the series should be used Thus if the user enters 3 then the program should calculate as being 4 4 3 4 5 NestedNested repetitionrepetition 3 Write a program that prints the following diamond shape You may use printfprintf statements that print either a single asterisk or a single blank Maximize your use of repetition with nested forfor statements and minimize the number of printfprintf statements 4 Write a

Write a C program that reads several numbers and uses the function round to nearest to round each of these numbers to the nearest integer The program should print both the original number and the rounded number 2 Write a program that reads three pairs of numbers and adds the larger of the first pair the larger of the second pair and the larger of the third pair Use a function to return the larger of each pair 3 A car park charges a 2 00 minimum fee to park for up to 3 hours and an additional 0 50 for each hour or part hour in excess of three hours The maximum charge for any given 24 hour period is 10 00 Assume that no car parks for more than 24 hours at a time Write a C program that will calculate and print the parking charges for each of 3 customers who parked their car in the car park yesterday The program should accept as input the number of hours that each customer has parked and output the results in a neat tabular form along with the total receipts from the three customers Car Hours Charge 1 1 5 2 00 2 4 0 2 50 3 24 0 10 00 TOTAL 29 5 14 50 The program should use the function calculate charges to determine the charge for each customer ExerciseExercise 7 7 MoreMore FunctionsFunctions 1 Write a program that uses sentinel controlled repetition to take an integer as input and passes it to a function even which uses the modulus operator to determine if the integer is even The function even should return 1 if the integer is even and 0 if it is not The program should take the value returned by the function even and use it 精品文档 6欢迎下载 to print out a message announcing whether or not the integer was even 2 Write a C program that uses the function integerPower1 base exponent to return the value of baseexponent so that for example integerPower1 3 4 gives the value 3 3 3 3 Assume that exponent is a positive non zero integer and base is an integer The function should use a for loop and make no calls to any math library functions 3 Write a C program that uses the recursive function integerPower2 base exponent to return the value of baseexponent so that for example integerPower2 3 4 gives the value 3 3 3 3 Assume that exponent is a positive non zero integer and base is an integer The function should make no calls to any math library functions Hint the recursive step will use the relationship baseexponent base baseexponent 1 and the base case will be when exponent is 1 since base1 base ExerciseExercise 8 8 ArraysArrays 1 Write a program that reads ten numbers supplied by the user into a single subscripted array and then prints out the average
