answer the following using C#

Design and program a Visual Studio Console project in C# that allows your user to enter a number. The program will examine the number to see if it is prime. If it is prime, it will print the next higher prime and the next lower primes to the console. If the number entered by the user is not prime, display a message to that effect.

All code should be written by you. Do not copy/paste any code from any other source.

Assume the input will be within the range 2 to (2^{^31}-1)

You should not validate the user input.

Write a program that acts as a basic calculator

• Assume the starting result is 0
• Ask the user for the operation to be performed
  • 0 – Exit
  • 1 – Add
  • 2 – Subtract
  • 3 – Multiply
  • 4 – Divide (Assume input will not be 0)
• Keep on performing the operation and showing the result until the user inputs the ‘0’ (exit) operation.
• You need to have everything written as functions
  • E.g. - You should only have the options listed once in the code
• You should have 4 different functions for each operation.
  • Any 2 of these functions should not return anything but instead use parameter passing by reference/pointers.
  • The other 2 functions should pass the parameter by value and have return statements (make sure to have a way to restrict the users to not make any changes to the original result variable).
• Your main function should be just the following lines

please use #include studio not ios.stream

int main(int argc, char* argv[])

{

    calculator();

    return 0;

}

/* Sample run of the program - Input and Output */

Write a program to carry out the stated task: When one of the buttons is pressed, the face changes to a smiling face [emoticon :-) ] or a frowning face [emoticon :-(]. Written in Visual Basic.

Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. Prompt the user for 12 months of highest and lowest.   Write two methods : one to calculate and return the average high and one to calculate and return the average low of the year. These methods MUST be your original code.   Your program should output all the values in the array and then output the average high and the average low.

Remember to submit all your .java files, .class files and screenshots of your code and output.

I cant not seem to get this right. I have tried and tried can I please get help. Thank you!

Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping() method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob() method. The format of the output is as follows: month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014 Observe the output of this program. Execute the program entering the following date: month = 9, day = 21, year = 2002 Observe the output of this program. The program is entered as the following: /* Program Name: BadDate.java Function: This program determines if a date entered by the user is valid. Input: Interactive Output: Valid date is printed or user is alerted that an invalid date was entered. */ import java.util.Scanner; public class BadDate { public static void main(String args[]) { // Declare variables String yearString; String monthString; String dayString; int year; int month; int day; boolean validDate = true; final int MIN_YEAR = 0, MIN_MONTH = 1, MAX_MONTH = 12, MIN_DAY = 1, MAX_DAY = 31; // This is the work of the housekeeping() method // Get the year, then the month, then the day Scanner input = new Scanner(System.in); // variable = input.nextLine(); // Convert Strings to integers // This is the work of the detailLoop() method // Check to be sure date is valid if( year <= MIN_YEAR ) // invalid year validDate = false; else if ( month < MIN_MONTH || month > MAX_MONTH ) // invalid month validDate = false; else if ( day < MIN_DAY || day > MAX_DAY ) // invalid day validDate = false; // This is the work of the endOfJob() method // Test to see if date is valid and output date and whether it is valid or not if( validDate == true ) { // Output statement } else { // Output statement } } // end of main() method } // end of BadDate class

C language only please

and please make a simple code

Write a function that will find whether there exist two integers that sum to the target integer. The function is to “return” three values.First, return “1” if the integers were found,return “-1” if your search was not successful.If you find two integers which add up to the target value, you should return their respective index position inside the array. Suggested prototype:int TwoSumFunction(int arr[], int size, int target, int*index1, int* index2);Inside TwoSumFunction:

•Pass the sorted array to the function. Set two pointers at the beginning and the end of thearray, then start moving the pointers inward while checking their sum. If it’s exactly the “target”, then we are done, and you can return 1. If it exceeds the “target”value, then any sum using the larger element is too large, so move the pointer corresponding to that element inward. If the sum is less than “target” value, then any sum using the lower element is too small, so move the pointer corresponding to that element inwards. If you are done with scanning the array and cannot find any two elements that sum up to “target” value, return -1.
