what while loop

Int fun () { int I = 0, a = 0; DO { A + = I; }while (I return; } Main disassembly code: Do{A + = I;00ad1a3c mov eax, dword ptr [A]00ad1a3f add eax, dword ptr [I]00ad1a42 mov dword ptr [a], eax} While (I 00ad1a45 cmp dword ptr [I], 64 h00ad1a49 JL

The do-while statement will loop at least once ,.Its syntax is as follows:Do {Statement (s)} While (booleanexpression );Simple instancePublic class mainclass {Public static void main (string [] args ){Int I = 0;Do {System. out. println (I );I ++;}

Explanation: i equal to 0. the Loop would run i would increase by 1 the loop runs. while i is less than, or equal to, 5, the loop would continue to run.

Conditions for continuing and terminating loops Do-while () will be executed before you can make sure that the loop executes at least once. Copy Code code as follows: PS c:powershell> do {$n =read-host} while ($n-ne 0) 10 100

A loop in JavaScript is used to execute the same piece of code for a specified number of times (or when the specified condition is true). JavaScript Switch Declaration If you want to choose to execute one of several blocks of code, you can use the

In a for loop, we can easily get the number of loops, because it appears as a condition. You can also obtain the following in the while statement: It is occasionally used in actual work.

Swift provides a similar control flow structure in all C languages. Includes for and while loops; if and switch conditional statements, break and continue jump statements, and so on. Swift also joins the for-in Loop statement, making it easier for
