- Needs to be done in C# language. Problem Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient, the following data should be entered: • The number of days spent in the hospital• The daily rate• Hospital medication charges• Charges for hospital services (lab tests, etc.) The program should ask for the following data if the patient was an out-patient: • Charges for hospital services (lab tests, etc.)• Hospital medication charges The program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other function accepts arguments for out-patient information. Both functions should return the total charges. Input Validation: Do not accept negative numbers for any data.Given the following FSM M, the correct statements are: a so s s a a b 90 q1 OL(M) = {w€ {a, b}* : w contains the substring ab}. OL(M) = {w€ {a,b}* : w does not contain the substring ab}. OL(M) = {w€ {a,b}* : w does not contain the substring aab}. OL(M) = {w€ {a,b}* : w contains the substring aab}.Matric Number: 2.

Four 6-letter words should be included in your program and have a theme. The word should be randomly selected when the user begins the game. After 7 incorrect guesses the user loses the game. The player wins by correctly guessing all of the letters that are part of the word. At each step, the program should remind the player of the letters he or she has already guessed, the program should not be case sensitive for input, but keep the output as uppercase letters. If the user enters the same letter twice that should count against them. Any help would be greatly appreciated as I'm stumped on how to complete this one.Look at the following code. int x = 7; int *ptr = &x;What will be displayed if you send the expression *iptr to cout? What happens if you send the expression ptr to cout?C Programming Language (Code With C Programming Language) Problem Title : Visible Trees There is a legend about a magical park with N × N trees. The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees. On the second column, Bunga can see…Kindly fix the errors in this assignmentI'm getting an error on error: expected ' ' before ' '} else if (grade == 'B') { (I cannot see the error)[ Here is the assignement ] Write an structure that will print a message based on the grade ( A,B,C,D,or F).
