------Java Training, Android training, iOS training,. NET training, look forward to communicating with you! -------"Loop Structure"1 , circular structure Introduction:Loops are executing the same block of code again and again2. Several conditions constituting the cyclic structure:cyclic control conditions;Loop Body: code block　The statement that can let the loop

One, while loopInstance: Public class test{ publicstaticvoid main (string[] args) { int i = 1; while (i) { System.out.println (i); I+ +; }}}Second, Do-while cycle Public class test{ publicstaticvoid main (string[] args) { int i = 1; Do { System.out.println (i); I++ ; } while (i); // Do-while Loop, first executed once, and then in

Title, do you define a new variable within the loop that is not each cycle? Reply to discussion (solution) It's hard to say, look at your needs. It's hard to say, look at your needs.Each time a local variable is needed in the loop, is the variable defined in the loop body or in the loop body? This depends on y

CONTINUE back to loop start/BreakJump out of the loop. The following is a simple example:1>DECLARE2> @testvalueAsINT;3> BEGIN--Set Variable initial value = 04> SET @testvalue = 0;--When the variable is less than 5 cycles5>While@testvalue 6> BEGIN--Variable increment7> SET @testvalue = @testvalue + 1;--if the variable = 2, then return to the beginning of the loop8

(1) While loop, do While loop: the difference between, while is to first judge the condition, then execute the statement. The Do while is executing the statement first, then judging the condition.while (loop condition expression) {do{EXECUTE statement; EXECUTE statement;}}while (cyclic conditional expression);(2) for loop:for (initialize expression;

if we want to do a lot of things, say we want to output hundreds of numbers, one output of the words not only cumbersome and time-consuming, inefficient. In this case, C # provides us with a much simpler way to output the loop. There are many types of loops, here I compare two loops: while loop for Loop. first of all , the while loop:the format of the while

While loop calculation rules: inner loop-outer loop !, While rule Num = 1 # value = 1While num Print (num) # The value of this 1 should be printedNum + = 1 # num + = 1 is equivalent to num plus 1, so this value is 2 in total.If num = 6: # if the program is terminated for 6, if it is not up to 6, the program will go over again until it reaches 6.BreakFor example:W

JavaScript as the scripting language for the client, generally speaking, is the speed of the first. The speed required depends on what makes the fastest. The circulation basically all language all has, is also the most commonly used, its embodiment, basically can represent the speed the embodiment. Basically 2 loops in javascript: For loop while loop The For loop
