c中的布尔帮助如何格式化random1是否与num1匹配

本文关键字:是否 random1 num1 匹配 格式化 布尔 帮助 | 更新日期: 2023-09-27 17:58:05

我被指示这样做:"跟踪布尔值中每个数字的匹配状态。检查所有三个布尔匹配变量,如果它们都为真,则我们与获胜数字匹配,退出while循环"

我已经完成了90%的任务,但我不确定我是否理解如何正确使用bool。

我假设他想让我检查randomNum1是否与userEnteredNum1匹配。

但我很难格式化。

我开始做这个:

     bool doTheyMatch1 = true

但我不知道从那里去哪里。所以我转到了一个更熟悉的"如果"语句

    if (random1 = userEntered1stDigit)

并得到"无法将类型int隐式转换为bool"错误。欢迎任何建议或有用的链接!

为了更有用,这里是我的全部代码:

       public Form1()
    {
        InitializeComponent();
    }
    //DECLARE CLASS LEVEL FIELD VARIABLES
    int CONST_cashPayoutPick3 = 500;
    int CONST_cashPayoutPick4 = 5000;
    int CONST_cashPayoutPick5 = 50000;
    private void myBtnGenRandomNumbers_Click(object sender, EventArgs e)
    {
        //DECLARE LOCAL VARIABLES
        int userEntered1stDigit = 0;
        int userEntered2ndDigit = 0;
        int userEntered3rdDigit = 0;

        //INPUT-VALIDATION
        //winning number: validate the 1st digit to be numeric, if not display error message and return
        if (int.TryParse(myTxtBox1stDigit.Text, out userEntered1stDigit))
        {
            //ok
        }
        else
        {
            MessageBox.Show("Please enter a number in the first box");
            return;
        }
        //winning number: validate the 2nd digit to be numeric, if not display error message and return
        if (int.TryParse(myTxtBox2ndDigit.Text, out userEntered2ndDigit))
        {
            //ok
        }
        else
        {
            MessageBox.Show("Please enter a number in the second box");
            return;
        }
        //winning number: validate the 3rd digit to be numeric, if not display error message and return
        if (int.TryParse(myTxtBox3rdDigit.Text, out userEntered3rdDigit))
        {
            //ok
        }

c中的布尔帮助如何格式化random1是否与num1匹配

简单,用== 更改=

在任何C风格中,=分配并返回分配的值,==执行布尔运算并返回truefalse

此外,你可以避免如果做

bool theyMatch = (numberOne == numberTwo) && (numberThree == numberFour) && (numberFive == numberSix);

此外,当您测试bool时,您不需要与true进行比较,因为它已经是bool

if(theyMatch == true)
{
   //your code
}
//Behaves the same as 
if(theyMatch)
{
   //Your code
}
