Problem Description

The contest starts now! How excited it is to see balloons floating around. You, one of the best programmers in HDU, can get a very beautiful balloon if only you have solved the very very very... easy problem.
Give you an operator (+,-,*, / --denoting addition, subtraction, multiplication, division respectively) and two positive integers, your task is to output the result.
Is it very easy?
Come on, guy! PLMM will send you a beautiful Balloon right now!
Good Luck!

 

 

Input

Input contains multiple test cases. The first line of the input is a single integer T (0<T<1000) which is the number of test cases. T test cases follow. Each test case contains a char C (+,-,*, /) and two integers A and B(0<A,B<10000).Of course, we all know that A and B are operands and C is an operator.

 

 

Output

For each case, print the operation result. The result should be rounded to 2 decimal places If and only if it is not an integer.

 

 

Sample Input

4+ 1 2- 1 2* 1 2/ 1 2

 

 

Sample Output

3-120.50

 

 

 

 

#include<stdio.h>int main(){ int  n,a,b; char k; scanf("%d",&n); while(n--) {    getchar();      scanf("%c %d%d",&k,&a,&b);    if(k=='+')        printf("%d\n",a+b);    if(k=='-')       printf("%d\n",a-b);     if(k=='*')      printf("%d\n",a*b);    if(k=='/')    {      if(a%b==0)          printf("%d\n",a/b);      else           printf("%.2f\n",a*1.0/b);    }  } return 0;}
