Instructions
Write a program that takes three strings:
-
The first and the third one are representations of base-10 signed integers that fit in an int.
-
The second one is an arithmetic operator chosen from:
+ - * / % -
The program must display the result of the requested arithmetic operation, followed by a newline. If the number of parameters is not 3, the program just displays a newline.
-
You can assume the string have no mistakes or extraneous characters. Negative numbers, in input or output, will have one and only one leading
-. The result of the operation fits in an int.
