Arithmetic Operations #1

Write a program that reads integers and operators of the C programming language from the standard input line by line, performs the operation indicated by the operator on the scanned/read values and writes the result to the standard output.

Input Specification

The input contains several test cases. The first line of the input contains a positive integer n indicating the number of test cases. Each of the following lines describes a test case. Each test case is a line in the form “x op y”, where x and y are integers, while op is one of the following integer arithmetic operators of the C programming language: +, -, *, /, %. The operands are separated from the operator by a space character.

Output Specification

For each test case, the program must write a single line containing the result of the operation x op y specified in the test case.
