make - included in Linux, MacOS, and Windows these days

the make program is now included with these operating systems

make string

when you type this command, the program "make" will look for a file called "string.c" to compile into the executable "string"


if you type the command "make hello" , the program make will look for a file called "hello.c" and compile it into the executable "hello"

clang -o string string.c -lcs50

in addition to " #include <cs50.h> "

you also have to "-lcs50"

where "l" stands for  "link"
