C/C++ do while loop with ExamplesC/C++ 中的循环在我们需要重复执行一个语句块时派上用场。与 while 一样,do-while 循环的执行也会根据测试条件终止。 do-while 循环和 while 循环之间的主要区别在于 do-while 循环中的条件在循环体的末尾进行测试,即 do-while 循环是退出控制的,而其他两个循环是入口控制...
Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘do-while’ loop to ‘20’; iteration is increment of counter variable ‘i’; condition is FALSE always as ‘0’ is provided that causes NOT to execute loop statements, but it is noted here in output that loop stateme...
Do While Loop Examples: Example 1: #include <stdio.h>intmain(void){intx=1;do{printf("%d\n",x);x++;}while(x<=10);} In this example, we’ve created a do while loop that will print out the numbers 1 through 10. The variable x is initialized to 1 and then incremented by 1 ea...
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。

Let us try to understand the behaviour of the while loop with a few examples.Example of do while LoopThe following program prints the Hello world message five times.Open Compiler #include <stdio.h> int main(){ // local variable definition int a = 1; // while loop execution do{ printf...
do{ //code to be executed }while(test condition); The body of the loop executes before checking the condition. If the test condition is true, the loop body executes again. Again the test condition is evaluated. The process repeats until the test condition becomes false. Example: do...wh...

Do while loop For loop 1. While Loop While Loop is used when we do not already know how often to run the loop. In While Loop, we write the condition in parenthesis “()” after the while keyword. If the condition is true then the control enters the body of the while Loop and runs...
