Experimental purposes: Familiarity with Boolean operations Proficiency in the use of branch statements and circular statement Control program execution process Implement multiple branches with Swich statements. Learn to control the loop termination condition, the normal exit of the loop, the use of the continue statement, the break statement. Experimental Steps and Contents: 1. Write a program, when the keyboard input "WASD" one of the four keys (b

inline function C + + unique, expanded internally, similar to define, but type checking for data types The inline function simply advises the compiler, and in general, the inline function has the following limitations:(1) cannot have recursion(2) cannot contain static data(3) cannot contain loops(4) cannot contain Swich and goto statements(5) cannot contain an arrayIf an inline function does not meet the above limit, the compiler will treat it as a n

. Zhang provides us with such a train of thought.1. Can you list the relevant fields in your database?2, since can be listed, you can selectively put the corresponding field Swich () ... case n:{}? Third, the program implementation code 1, list all the tables in the database Try{DatabaseMetaData Dbmd = Conn.getmetadata (); Specify the list of required informationString[] types = {"TABLE"};RS1 = Dbmd.gettables (null, NULL, "%", types);while (Rs1.next (
