hdu-Balloon Comes!一道水题的报告
今天闲来无事,想刷几道水题来增加自信心。但是在刷这道水题时,我发现了自己的一个知识漏洞!!!!
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 -1 2 0.50 这个题目是个十足的水题,但是我今天却在这个题目上卡壳了。不过通过这道题,我对于%c这个符号有了新的认识。
先附上我最后ac的代码吧
