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...
It is an entry-controlled loop. 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...
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); 请注意,条件表达式出现在循...
C programming has three types of loops. for loop while loop do...while loop In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do..while loop. while loop The syntax of the while loop is: while (testExpression) { // the body of the...
有如下VB程序段[1]:S=0C=1Do While C<=6S=S+CC=C+1Loop该程序运行结束后,变量C的值为 7,变量S的值为 21.
Do…Loop循环 功能:当循环“条件”为真(While条件)或直到指定的循环结束“条件”(Until〈条件〉)为真之前重复执行“循环体”。 形式1: Do [While| Until〈条件〉] [〈循环体〉] [Exit Do] Loop 形式2: Do [〈循环体〉] [Exit Do] Loop [ ...
// 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. ...
结果1 题目 12.在DO WHILE循环结构中,LOOP命令的作用是( )。 A.退出过程,返回程序开始处 B.转移到DO WHILE语句行,开始下一个判断和循环 C.终止循环,将控制转移到本循环ENDDO后面的第一条语句继续执行 D.终止程序执行 相关知识点: 试题来源: 解析 12.B 反馈 收藏 ...
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...
答案:C. 解:当计算机遇到While语句时,先判断条件的真假,若条件符合,就执行循环体; 若条件不符合,则不执行循环体,直接跳到END后的语句. 故选C. 本题是一道考查循环语句的题目,掌握Do Loop语句的特点以及循环语句的结构是解答本题的关键; 首先根据题设条件,由Do Loop语句的特点,当计算机遇到While语句时,先判断条...
