while 和 do while 都是 C 语言中的循环语句,它们的主要区别在于循环体执行的顺序。 while 循环首先检查循环条件,只有当条件为真时才执行循环体。因此,如果条件一开始就为假,那么循环体将永远不会执行。而如果条件一直为真,那么循环将一直执行下去。 while: 你欠我钱,我走路上,前面一人,我先看清楚这个人是不是你,不是就不打
1.很多情况下,while和do while可以互换 2.while特点:如果一开始的条件不成立,永远不会执行循环体 do while特点:不管一开始的条件是否成立,至少会执行一次循环体 3.最好使用while */ #include <stdio.h> int main() { int i = 0; /* while (i<0) { i++; // 5 }*/ do { i++; // 5 } wh...
} 以上例子,循环寻找一个目标,直到寻到为止。 代码 //do while privatevoidbutton1_Click(objectsender, EventArgs e) { DialogResult result; loop: do { //code result=MessageBox.Show("是否继续寻找?","", MessageBoxButtons.OKCancel,MessageBoxIcon.Question); if(result==DialogResult.OK) { listBox1.Item...
