In C#, complete each individual exercise separately:

1.)A method IncreaseSalary has been defined. It accepts a single parameter of type int. Assume that a variable Salary of type int has been declared and initialized. Invoke the method IncreaseSalary and pass it the variable Salary by reference.

2.)Write the definition of a public method printGrade, which has a char parameter and returns nothing. The method prints on a line by itself the message string Grade: followed by the char parameter (printed as a character) to standard output. Don't forget to put a new line character at the end of your line.

3.)Given the integer variables x and y, write a fragment of code that assigns the larger of x and y to another integer variable max.

4.)Write the definition of a method min that has two int parameters and returns the smaller.

5.)Write the definition of a public method printLarger, which has two int parameters and returns nothing. The method prints the larger value of the two parameters to standard output on a single line by itself.
