1.1       root        1: #print
                      2: (Section 1.1)
                      3: Now write a C program that prints two lines,
                      4: the first of which says "hello" and the second
                      5: "goodbye".  Don't forget those \n delimiters.
                      6: Compile and test it.  When satisfied,
                      7: type "ready".
                      8: #once #create Ref
                      9: hello
                     10: goodbye
                     11: #user
                     12: a.out >test
                     13: #cmp test Ref
                     14: #succeed
                     15: Here is one possible solution to compare against yours.
                     16: 
                     17: main()
                     18: {
                     19:        printf("hello\n");
                     20:        printf("goodbye\n");
                     21: }
                     22: 
                     23: You could also combine the two messages into one
                     24: call to printf, like
                     25: 
                     26:        printf("hello\ngoodbye\n");
                     27: 
                     28: but this is harder to read at a glance.
                     29: #log
                     30: #next
                     31: 1.1c 10
