杭电OJ | 1170 一定要记得getchar吸收换行符！

1170

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

-1

2

0.50

要点：注意输出和getchar吸收换行！！！再忘记getchar我就！再学一遍...

#include <stdio.h>
int main(){
	int inputnum;
	scanf("%d",&inputnum);
	getchar();
	for(;inputnum!=0;inputnum--){
		int a,b;
