Introduction
In this lab, you will learn about using macros with the +
and *
symbols in the argument list to indicate repetition. Specifically, the example provided demonstrates how to use $(...),+
to match one or more expressions separated by commas. The macro, find_min!
, calculates the minimum value among a variable number of arguments.
Note: If the lab does not specify a file name, you can use any file name you want. For example, you can use
main.rs
, compile and run it withrustc main.rs && ./main
.
