Q4-Write a program to convert a test score into its equivalent letter grade (use else if CONSTRUCT):
(1) Prompt the user for a string that contains two strings separated by a comma • Examples of strings that can be accepted: • Jill, Allen • Jill, Allen • Jill, Allen Ex: Enter input string: Jill, Allen (2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings Ex: Enter input string: Jill Allen Error: No comma in string. Enter input strings ming Fundamentals home > 9.11: LAB: Warm up: Parsing strings Ex: (3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. Enter input string: Jill, Allen First word: Jill Second word: Allen (4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit Ex: Enter input string: Jill, Allen First word: Jill Second word: Allen 0 Enter input string: Golden Monkey , First…
3. The bin packing problem is to pack the objects of various weights into containers. Assume that each container can hold a maximum of 10 pounds. The program uses an algorithm that places an object with the largest weight into the first bin in which it would fit. Your program should prompt the user to enter the total number of objects and the weight of each object. The program displays the total number of containers needed to pack the objects and the contents of each container. Here is a sample run of the program: Enter the number of objects about itinerary with the following members: 1. A data field named flgihts of the List type. The list contains the flights for the itinerary in increasing order of departure Time. A constructor that creat: 6 Enter the weights of the objects: 7 5 2 3 5 8 Container 1 contains objects with weight 8 2 Container 2 contains objects with weight 7 3 Container 3 contains objects with weight 55
2. Write a program that asks the user to input 4 numbers and displays the values in (a) ascending and (b) descending orders.
(1) Prompt the user to enter a string of their choosing. Store the text in a string. Output the string. Ex: Enter a sample text: We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue! You entered: We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue! (2) Implement a PrintMenu() function, which has a string as a parameter, outputs a menu of user options for analyzing/editing the string, and returns the user's entered menu option. Each option is represented by a single character. If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call PrintMenu() in the main() function. Continue to call…
