- The purpose of this exercise is to demonstrate the importance of testing an application thoroughly. Open the FixIt Solution.sln file contained in the VB2017\Chap04\FixIt Solution folder. The application displays a shipping charge that is based on the total price entered by the user, as shown in Figure 4-64. Start the application and then test it by clicking the Display shipping button. Notice that the Shipping charge box contains $13, which is not correct. Now, test the application using the following total prices: 100, 501, 1500, 500.75, 30, 1000.33, and 2000. Here too, notice that the application does not always display the correct shipping charge. (More specifically, the shipping charge for two of the seven total prices is incorrect.) Open the Code Editor window and correct the errors in the code. Save the solution and then start and test the application.Write an application that allows a user to enter any number of student test scores until the user enters 999. If the score entered is less than 0 or more than 100, display an appropriate message and do not use the score. After all the scores have been entered, display the number of scores entered, the highest score, the lowest score, and the arithmetic average. Save the file as TestScoreStatistics.cpp.Write an application that reads the (x,y) coordinates for two points. This should prompt for and read each of the four values individually. Compute the distance between the two points using the following formula: Distance=(?2−?1)2+(?2−?1)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
- A Sub procedure named GetEndInv is passed four Integer variables from its calling statement. The first three variables store the following three values: beginning inventory, number sold, and number purchased. The procedure should use these values to calculate the ending inventory, and then store the result in the fourth variable. Which of the following procedure headers is correct? a. Private Sub GetEndInv(ByVal intB As Integer, ByVal intS As Integer, ByVal intP As Integer, ByRef intFinal As Integer) b. Private Sub GetEndInv(ByVal intB As Integer, ByVal intS As Integer, ByVal intP As Integer, ByVal intFinal As Integer) c. Private Sub GetEndInv(ByRef intB As Integer, ByRef intS As Integer, ByRef intP As Integer, ByVal intFinal As Integer) d. Private Sub GetEndInv(ByRef intB As Integer, ByRef intS As Integer, ByRef intP As Integer, ByRef intFinal As Integer)Now code an application that declares a purchase object and prompts the user for purchase details. When this prompt is made, do not allow the user to proceed until a number between 1000 and 6000 inclusive has been entered. When the system prompts for a sale amount, it must not proceed until the user has entered a non-negative value. In the event a valid purchase object has been created, display the object’s invoice number, sale amount and sales taxDo it soon i will rate Create a Console application named Debug5DA Save the application in the FirstInitialLastnameCSUnit5D folder. // Uses DisplayAddress method three times using static System.Console; class Debug5DA { static void Main() { DisplayAddress; Writeline("Welcome to Earth!"); DisplayAddress; WriteLine("3rd Rock from the Sun!"); DisplayAddres; } public void DisplayAddress() { WriteLine("------------------------------"); WriteLine("Visit us on the web at:"); WriteLine("www.WelcomeToEarth.com"); WriteLine("******************************"); } }
- A website requires that passwords only contain alphabetic characters or numbers. For each character in codeStr that is not an alphabetic character or number, replace the character with 'x'. C++ Ex: If the input is 3!fgMB, then the output is: Updated password: 3xfgMB Note: isalpha() returns true if a character is alphabetic, and false otherwise. Ex: isalpha('a') returns true. isalpha('8') returns false. isdigit() returns true if a character is a digit, and false otherwise. Ex: isdigit('8') returns true. isdigit('a') false #include <iostream>#include <string>using namespace std; int main() { string codeStr; unsigned int i; cin >> codeStr; codeStr.at(1) = 'x'; for (i + 0; i < codeStr.size(); ++i) { if (isalpha (codeStr.at(1))) { i += 1; }} cout << "Updated password: " << codeStr << endl; return 0;} cout<<"Updated password: "<<codeStr<<endl;Each of the following files in the Chapter.07 folder of your downloadable student files has syntax and/or logical errors.
