- (C#) to create a program, name it PRGYOURNAMEFA1, that implements a search and replace function recursively. Your program should allow a user to enter a string , a substring to be replaced in the entered string and a character/s to replace the found substring Program StructureA main class that implements the logic of the program – name this class TestSearchReplaceAdd a class named SearchReplace to the main class with two methods, including:SearchSubstring()- return methodReplaceSubString() - void method The two method should be called using an object in the main class. DONT CREATE THE TWO METHODS IN THE MAIN CLASSSample Outputarrow_forward1. (Dice simulation) Java/C++ program that computes the exact probability distribution for the sum of two dice. Run experiments to validate this calculation simulating N dice throws, keeping track of the frequencies of occurrence of each value when you compute the sum of two random integers between 1 and 6. How large does N have to be before your empirical results match the exact results to three decimal places?arrow_forward(C Language) Write a recursive function called PrintNumPattern() to output the following number pattern. Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline.arrow_forward
- (CODE THIS IN C) DO NOT CODE IN C++arrow_forward(C++) Write a function definition called quotient that takes as its parameters two decimal values, numer and denom, to divide. Remember that division by 0 is not allowed. If division by 0 occurs, display the message "NaN" to the console, otherwise display the result of the division and its remainder.arrow_forwardplease help me (C++Question) how can I write this code here please helparrow_forward
- (C PROGRAM ONLY) 1. Undercover Mission Planby CodeChum Admin Hi Programmer, I'm Agent J. I'm preparing for an undercover mission going to the enemy's base. However, it seems that my plans are still missing some few details. Can you help me with this? Instructions: In the code editor, there's a main() function that calls the recursive printPlan() function.The printPlan() function already contains some code but it seems to be missing a base case that makes it stop. Supposedly, this printPlan() function should only print the plan by n / 2 number of times. For example, if n is 10, then this should only print the plan 5 times or if n is 20, then this should only print the plan 10 times.Fix this function by adding the correct condition in its base case.For this problem, assume that the value of n is always divisible by 2.Input 1. Value of n Output Enter n: 6Plan by Agent J.Plan by Agent J.Plan by Agent J.arrow_forward(C Language) Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substring() function to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3-1-1990.arrow_forward(C PROGRAMMING ONLY) 2. Weird Treasure Chestby CodeChum Admin I'm now in the middle of the jungle when I saw this weird treasure chest. It seems that if I properly place the address of a certain number, I get a very weird result! Instructions: In the code editor, you are provided with a treasureChestMagic() function which has the following description:Return type - voidName - treasureChestMagicParameters - an address of an integerDescription - updates the value of a certain integer randomlyYou do not have to worry about how the treasureChestMagic() function works. All you have to do is ask the user for an integer and then call the treasureChestMagic() function, passing the address of that integer you just asked.Finally, print the updated value of the integer inputted by the user.Input 1. An integer Output Enter n: 10Treasure Chest Magic Result = 13arrow_forward
- (Chapter 6, User-Defined Functions) Write in c++ a value-returning function, isVowel, that returns the value true if a given character is avowel and otherwise returns false.arrow_forward(Apartment problem) A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program in C++ that prompts the user to enter: The total number of units. The rent to occupy all the units. Amount to maintain a rented unit. The increase in rent that results in a vacant unit. The program then outputs: The number of units to be rented to maximize the profit The maximum profit Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.arrow_forward(Signal Handling) Read the documentation for your compiler to determine what signals are supported by the signal-handling library (). Write a program that contains signal handlers for the standard signals SIGABRT and SIGINT. The program should test the trapping of these signals by calling function abort to generate a signal of type SIGABRT and by having the user type c ( C on OS X) to generate a signal of type SIGINT.arrow_forward
