Difference between while and do-while loop in C, C++, Java while 循环: 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() { i...
do-while 语句 **do-while语句基本语法格式do{ 语句; }while(布尔表达式); 其中dowhile是关键字,先执行do中的语句,在判断while表达式的值,若值为true则继续执行;否则循环结束。 ** 例如:用do-while语句求 1-10的和 Java-while循环语句 while与dowhile循环结构,格式简单,方便记忆。一、while结构比较:while(循环...
Then, the test expression i <= 5 will be false and the loop terminates. do...while loop The do..while loop is similar to the while loop with one important difference. The body of do...while loop is executed at least once. Only then, the test expression is evaluated. The syntax of...
In this tutorial, we will learn the use of while and do...while loops in C++ programming with the help of some examples. Loops are used to repeat a block of code
While loop is mainly used when we do not know how many times a statement will be executed. In such a case, the number of iterations is unknown, and it depends on the condition inside the while loop.In C++, we can make use of nested while loops as well. Also, there are infinite loo...
