Write a C program that contains two functions: one that calculates the counts from standard input, and another that calculates the counts from a string. This file should counts the number of letters, digits, other characters, and total characters from the input.If the user does not provide any additional command line arguments, count the occurrences from standard input. If there is an additional command line argument, count the occurrences in the string provided on the command line.

(Data processing) Write a C++ program that reads the file created in Exercise 4 one record at a time, asks for the number of hours each employee worked each month, and calculates and displays each employee’s total pay for the month.

(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.

Each of the following files in the Chapter.05 folder of your downloadable student files has syntax and/or logical errors. In each case, determine the problem, and fix the program. After you correct the errors, save each file using the same filename preceded with Fixed. For example, save DebugFive1.cs as FixedDebugFive1 .cs. a. DebugFive1.cs b. DebugFive2.cs c. DebugFive3.cs d. DebugFive4.cs

In Chapter 4, you created a program that generates a random number, allows a user to guess it, and displays a message indicating whether the guess is too low, too high, or correct. Now, create a modified program called GuessingGame2 in which the user can continue to enter values until the correct guess is made. After the user guesses correctly, display the number of guesses made. Recall that you can generate a random number whose value is at least min and less than max using the following statements: Random ranNumber = new Random(); int randomNumber; randomNumber = ranNumber.Next(min, max);

What does function sqrt do? Which header file must be included to use the function sqrt? (3)

In this chapter, you learned that although a double and a decimal both hold floating-point numbers, a double can hold a larger value. Write a C# program named DoubleDecimalTest that declares and displays two variables-a double and a decimal. Experiment by assigning the same constant value to each variable so that the assignment to the double is legal but the assignment to the decimal is not. In other words, when you leave the decimal assignment statement in the program, an error message should be generated that indicates the value is outside the range of the type decimal, but when you comment out the decimal assignment and its output statement, the program should compile correctly.

In previous chapters, you created applications for the Greenville Idol competition. Now, modify the version of the GreenvilleRevenue program created in Chapter 5 so that after the user enters the number of contestants in this competition, the user is prompted for the appropriate number of contestant names and a code for each contestant that indicates the type of talent: S for singing, D for dancing, M for playing a musical instrument, or O for other. Make sure that all entered codes are valid, and if not, reprompt the user to enter a correct code. After contestant data entry is complete, display a count of each type of talent. Then, continuously prompt the user for a talent code until the user enters a sentinel value. With each code entry, display a list of the contestants with that code, or display a message that the code is not valid and reprompt the user.

(Program) Write a C++ program that accepts a string from the user and then replaces all occurrences of the letter e with the letter x.

Write a C# program named ProjectedRaises that includes a named constant representing next years anticipated 4 percent raise for each employee in a company. Also declare variables to represent the current salaries for three employees. Assign values to the variables, and display, with explanatory text, next years salary for each employee.
