How to build

How to run

./math_server -port=9090

This launches the server, listening on port 9090. If you don't specify a port, it defaults to 8080.

API

There's a single query parameter expression that expects an arithmetic expression. (, ), +, -, *, and / are supported. Order of operations is respected. There must be a space between each operator and number. If the expression is valid, the result is returned as a string with a status code 200. If the expression is invalid, an error message is returned with a 400 status code.

From the command line:

curl -G --data-urlencode "expression= ( 2 + 2 ) * -10" localhost:8080

curl -G --data-urlencode "expression= 2 + 2 * -10" localhost:8080
