Here, you can observe the difference between the two loops −Output of while loop: Output of do-while loop: b: 11 Note that the while loop doesn't take any iterations, but the do-while executes its body once. This is because the looping condition is verified at the top of the loop...
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。
do..while循环类似于while循环,但有一个重要区别。do...while循环主体至少执行一次。执行一次后,才对测试表达式求值。 do...while循环的语法为: 示例 do { //循环体内的语句 } while (testExpression); do... while循环如何工作? do ... while循环的主体执行一次。只有这样执行一次后,才对测试表达式求值。
Following is the flowchart for do-while loop: We initialize our iterator. Then we enter body of the do-while loop. We execute the statement and then reach the end. At the end, we check the condition of the loop. If it isfalse, we exit the loop and if it istrue, we enter the lo...
入口控制循环:在这种类型的循环中,测试条件在进入循环体之前进行测试。 For 循环和 While 循环是入口控制循环。 退出受控循环:在这种类型的循环中,测试条件在循环体的末尾进行测试或评估。因此,循环体将至少执行一次,而不管测试条件是真还是假。 do – while 循环是退出控制循环。
tips for loops: 如果有固定次数,用for;如果必须执行一次,用do-while;其他情况用while。 break:跳出循环 continue:跳过循环这一轮剩下的语句进入下一轮 goto语句:跳出多层循环,跳到out位置。 (猜测:使用goto语句必须要return 0。因为我没加return 0,会报错。) ...
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...
Thedo...whileloop is almost the same as while loop except for one difference. As an important point, thedo...whileloop is always executed at least once, unlike the other loops. This happens because the loop runs for the first time and then at the end, the condition is checked to be...
The while loop is one of the most frequently used types of loops in C. The other looping keywords in C are for and do-while.The while loop is often called the entry verified loop, whereas the do-while loop is an exit verified loop. The for loop, on the other hand, is an ...
do{}while(1)语句使用的不多,因为也会需要在执行语句之后判断条件,会浪费单片机的资源。 4.goto语句 loop: //code goto loop; 实际的嵌入式开发中,很少使用goto语句,但是也可以使用goto语句编写死循环。 #include<iostream> using namespace std; int main() { //用goto实现infinite loops(死循环) A: cout...
