What will be the output for the following program

Question

public class Calculator { public int Sum(int x, int y) { return x + y; } } public class Client1 { public void Operation() { int a = 4; int b = 5; //Find Sum of a and b and formula of sum will be x+y for client1 } } public class Client2 { public void Operation() { int a = 4; int b = 5; //Find Sum of a and b and formula of sum will be 3x+4y+7 for client2 } } Can anyone tell me how i can acheive this in c# ? Thank you

Hi, You can Access Sum by creating object of class calculator and pass a and b as a parameter. Please try below code: public class Calculator { public int Sum( int x, int y) { return x + y; } } public class Client1 { public void Operation() { int a = 4; int b = 5; //Find Sum of a and b and formula of sum will be x+y for client1 Calculator c= new Calculator(); int sum = c.Sum(a, b); Console.WriteLine(sum); } } public class Client2 { public void Operation() { int a = 4; int b = 5; //Find Sum of a and b and formula of sum will be 3x+4y+7 for client2 Calculator c= new Calculator(); int sum = c.Sum(3*a, 4*b)+7; Console.WriteLine(sum); } }

public class Calculator { public int Sum( int x, int y) { return x + y; } } public class Client1 { public void Operation() { // Its general normal way. int a = 4; int b = 5; Calculator obj = new Calculator(); int sum = obj.Sum(a, b); Console.WriteLine(sum); } } public class Client2 { public void Operation() { //complex comes like : 3x + 4y + 7 int a = 4; int b = 5; // a, b values after multiply. a = 3 * 4; //For x value b = 4 * 5; //For y value Calculator obj = new Calculator(); int sum = obj.Sum(a, b) + 7; Console.WriteLine(sum); } } If it helps, Mark as answer. Else come up with your query. Thank you.
