Problem:
Simple Calculator

Write a program which reads two integers a, b and an operator op, and then prints the value of a op b.

The operator op is '+', '-', '*' or '/' (sum, difference, product or quotient). The division should truncate any fractional part.

Input

The input consists of multiple datasets. Each dataset is given in the following format.

a op b

The input ends with a dataset where op = '?'. Your program should not process for this dataset.

Output

For each dataset, print the value in a line.

Constraints

0 ≤ a, b ≤ 20000

No divisions by zero are given.

Sample Input 1

1 + 2
56 - 18
13 * 2
100 / 10
27 + 81
0 ? 0

Sample Output 1

3
38
26
10
108

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int N=0;
        int[] a= new int[100000];
        int[] b= new int[100000];
        int[] ans= new int[100000];
        String[] op= new String[100000];
        for(int i=0;;i++){
            a[i]=sc.nextInt();
            op[i]=sc.next();
            b[i]=sc.nextInt();
            if(op[i].equals("+"))ans[i]=a[i]+b[i];
            else if(op[i].equals("-"))ans[i]=a[i]-b[i];
            else if(op[i].equals("*"))ans[i]=a[i]*b[i];
            else if(op[i].equals("/"))ans[i]=a[i]/b[i];
            else break;
            N++;
        }
        for(int i=0;i<N;i++)System.out.println(ans[i]);
        sc.close();
