This program builds with a standard "g++ -o exe file" call but there is an included makefile.
There are a couple options.
1) You can use "make run FILENAME={file_to_run}" to build and run the program called "CoinChange"
replacing {file_to_run} with the name of your coin file without extensions.
Ex.-"make run FILENAME=coins" To build CoinChange then run coins.txt.
2) You can just use default "make" to build the program "CoinChange". Then you can run it using
"./CoinChange" and the name of the file without extensions.
Ex.-"make"
-"./CoinChange coins" To build CoinChange then run coins.txt
