The program ends if the input is End". Note that printf ("%s", str ) is used to print the content of str You can use string compare (strcmp) as described below (include the string.h header) strcmp (s1, s2) stremp ("End", "End") strcmp ("Test", "Test1") strcmp ("Test2","Testl") strcmp (str, "Init") // test character by character // returns 03s1-s2 // returns -1s1 execution time 22.370 s ress any key to continue Fig
