Question

Write a console-based program ( C # ) that asks a user to enter a number between 1 and 10. Check if the number is between the range and if not ask the user to enter again or quit. Store the values entered in an array. Write two methods. Method1 called displayByVal should have a parameter defined where you pass the value of an array element into the method and display it. Method2 called displayByRef should have a parameter defined where you pass the array by reference and display its content. Call both methods from you main program.

Answer 1

class MainClass {

public static void Main (string[] args) {

int []arr=new int[1];

int value=0;

//loop until user enters valid value

while(true){

Console.WriteLine ("Enter value between 1-10");

value= Convert.ToInt32(Console.ReadLine());

if(value>=1 && value<=10){

break;

}

Console.WriteLine ("Invalid! Please try again");

}

//storing the value in array and calling methods

arr[0]=value;

displayByVal(arr[0]);

displayByRef(arr);

}

// method receiving call by value

public static void displayByVal(int val){

Console.WriteLine ("Printing using Call by value: "+val);

}

//method printing using call by reference

public static void displayByRef(int []arr){

Console.WriteLine ("Printing using Call by reference: "+arr[0]);

}

}
