22. Input 2 numbers and also Input your choice if your choice is 1 then Addition of two numbers. if your choice
is 2 then Subtractions of two numbers, if your choice is 3 then Multiplication of two numbers, if your choice
is 4 then Division of two numbers in c++ if program

Import java.util.*;
class number
{
public static void main();
{
Scanner in = new Scanner (System.in);
int n1, n2, c, a;
System.out.println(“Enter any two number”);
n1 = in.nextInt();
n2 = in.nextInt();
System.out.println(“Enter your choice”)
c = in.nextInt();
switch(c)
{
case 1:
a = n1 + n2;
System.out.printn(“sum of two number = “ +a);
case 2:
a = n1 – n2;
System.out.println(“Subtraction of two number = ” + a);
case 3:
a = n1 * n3;
System.out.println(“Multiplication of two number = ” + a);
case 4:
a = n1 / n2;
System.out.println(“Division of two number = ” + a);
default:
System.out.println(“Wrong Choice”);
}
}
}
or this program can be written in this form also
Import java.util.*;
class number
{
public static void main();
{
Scanner in = new Scanner (System.in);
int n1, n2, c, a;
System.out.println(“Enter any two number”);
n1 = in.nextInt();
n2 = in.nextInt();
System.out.println(“Enter your choice”)
c = in.nextInt();
if (c == 1)
{
a = n1 + n2;
System.out.println(“Addition of two number =” + a);
}
else if(c == 2)
{
a = n1 – n2;
System.out.println(“Substraction of two number =” + a);
}
else if (c == 3)
{
a = n1 * n2;
System.out.println(“multiplication of two number =” + a);
}
else if (c == 4)
{
a = n1 / n2;
System.out.println(“division of two number =” + a);
}
else
{
System.out.println(“Wrong Choice”);
}
}
}
