The next condition, in the else if statement, is also false, so we move on to the else condition since condition1 and condition2 is both false - and print to the screen "Good evening". However, if the time was 14, our program would print "Good day." When C reaches a break keyword, it breaks out of the switch block. This will stop the execution of more code and case testing inside the block. When a match is found, and the job is done, it's time for a break. There is no need for more testing. A break can save a lot of execution time because it "ignores" the execution of all the rest of the ... Explicit Conversion. Explicit conversion is done manually by placing the type in parentheses () in front of the value.
