int z;
float c,op=0;






//Create Scanner to obtain input from command window(console)
// Scanner s=new Scanner();
Scanner s=new Scanner(System.in);


System.out.print("Enter first ");
x=s.nextInt();

// Scanner op=new Scanner();
Scanner op1=new Scanner(System.in);

System.out.print("c ");

System.out.print(" second number ");
y=s.nextInt();


if (op=='+')
{
z=x+y;
System.out.println("The summation is"+z);
}
else
if(op=='-')
{
z=x-y;
System.out.println("The subtraction is"+z);
}
else
if(op=='/')
{
z=x/y;

System.out.printf("The division is"+z);
}
else
if(op=='*')
{
z=x*y;

System.out.println("The multiplication is"+z);
}

}
