Python - While Loops - A while loop in Python programming language repeatedly executes a target statement as long as the specified boolean expression is true. This loop starts with while keyword followed by a boolean expression and colon symbol (:). Then
在Python中,在编程构造之后由相同数量的字符空格缩进的所有语句被认为是单个代码块的一部分。 Python使用缩进作为分组语句的方法。 流程图 (Flow Diagram) 这里,while循环的关键点是循环可能永远不会运行。 当测试条件并且结果为假时,将跳过循环体并且将执行while循环之后的第一个语句。 例子(Example) #!/usr/bin/...
Python whileTrue:if<expr1>:# One condition for loop terminationbreak...if<expr2>:# Another termination conditionbreak...if<expr3>:# Yet anotherbreak In cases like this, where there are multiple reasons to end the loop, it is often cleaner tobreakout from several different locations, rather...
while loop in Java may contain a single, compound, or empty statement. The loop repeats while the test expression or condition evaluates to true. When the expression becomes false, the program control passes to the line just after the end of the loop-body code. Here is a simple diagram ...
Flow Diagram of while loop Example of while loop #include<stdio.h>intmain(){intcount=1;while(count<=4){printf("%d ",count);count++;}return0;} Output: 1234 step1:The variable count is initialized with value 1 and then it has been tested for the condition. ...
Flow-chart of while loop in C In the while loop, evaluation of the controlling expression takes place before each execution of the loop body. How does the while loop work? Step 1. The while loop evaluates the controlling expression. Step 2. If the controlling expression is false, the body...
C++ do...while loop - Unlike for and while loops, which test the loop condition at the top of the loop, the do...while loop checks its condition at the bottom of the loop.
The flow diagram below shows the way the loop works. Let’s see how to work with a FOR loop – we will create a single loop and double loop. Example: Public Sub forloop1() Dim a, i As Integer a = 5 For i = 0 To a
