### 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.
|
||
|
|
|
||
|
|
Example of output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine/test$ go build
|
||
|
|
student@ubuntu:~/piscine/test$ ./test "123" "*" 456
|
||
|
|
56088
|
||
|
|
student@ubuntu:~/piscine/test$ ./test "9828" "/" 234
|
||
|
|
42
|
||
|
|
student@ubuntu:~/piscine/test$ ./test "10" "+" "-43"
|
||
|
|
33
|
||
|
|
student@ubuntu:~/piscine/test$ ./test
|
||
|
|
|
||
|
|
student@ubuntu:~/piscine/test$
|
||
|
|
```
