+** Source:  test1.c
+**
+** Purpose: 
+** Check three cases of searching for a string within a string.  First when
+** the string is contained, check that the pointer returned points to it.
+** Then when it isn't contained, ensure it returns null.  And when the string
+** we're searching for is empty, it should return a pointer to the string 
+** we're searching through.Test #1 for the strstr function
+**
