2. do – while loop in C It also executes the code until the condition is false. In this at least once, code is executed whether the condition is true or false but this is not the case with while. While loop is executed only when the condition is true. Syntax: do{ //code }whil...
The while loop in C is used when we don’t know the number of iterations.while loop Flowchart Syntax while(test condition){ //code to be executed } If the test condition inside the () becomes true, the body of the loop executes else loop terminates without execution. The process ...
while 循环是一种控制流语句,它允许根据给定的布尔条件重复执行代码。 while 循环可以被认为是一个重复的 if 语句。语法: while(booleancondition) { loop statements... } 流程图: 例子: C实现 #include<stdio.h> intmain() { inti=5; while(i<10){ printf("GFG "); i++; } return0; } C++ 实现...
// The loop goes while x < 10, and x increases by one every loop for(intx = 0; x < 10; x++ ) { // Keep in mind that the loop condition checks // the conditional statement before it loops again. // consequently, when x equals 10 the loop breaks. ...
while(condition); Note:The semicolon;after thewhilecondition is required! Do/While Example The example below uses ado/whileloop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested. ...
4.do whileloop in C In some situations it is necessary to execute body of the loop once before testing the condition. Such situations can be handled with the help ofdo-whileloop. Thedostatement evaluates the body of the loop first and at the end, the condition is checked usingwhilestatemen...
Do While...Loop 语句是条件为True时循环 Do until...Loop 语句是直到条件变成True时才停止循环 如果事先知道循环次数,应该使用For循环,据说它比Do循环速度快 不知道起点和终点,需要在循环内计算结果出来以后才能判断是否该终止循环的,用Do Loop循环。反之,如果很明确需要循环计算的次数,则用For……Next……计量循...
C 循环 不像for和while循环,它们是在循环头部测试循环条件。在 C 语言中,do...while循环是在循环的尾部检查它的条件。 do...while循环与 while 循环类似,但是 do...while 循环会确保至少执行一次循环。 语法 C 语言中do...while循环的语法: do{statement(s);}while(condition); ...
Output of while loop: Output of do-while loop: b: 11 Note that thewhileloop doesn't take any iterations, but thedo-whileexecutes its body once. This is because the looping condition is verified at the top of the loop block in case ofwhile, and since the condition is false, the progr...
c loops while-loop do-while do-loops 我有一个任务(目前正在研究循环语句,所以我处于初学者阶段),它要求编写一个程序来反转一个整数,因此它必须有 do语句。 输出应为(示例): Enter a number: 4568 The reversal is: 8654 请记住,由于我遵循我的书,到目前为止,我已经研究和了解了最基本的+选择和循环语句...
