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
}
else
{
MessageBox.Show("Please enter a number in the third box");
return;
}
//INITIALIZE ANY VARIABLES
userEntered1stDigit = int.Parse(myTxtBox1stDigit.Text);
userEntered2ndDigit = int.Parse(myTxtBox2ndDigit.Text);
userEntered3rdDigit = int.Parse(myTxtBox3rdDigit.Text);
//GOOD SO FAR
//PROCESSING
//setup your own Random number generator object
int random1 = 0;
int random2 = 0;
int random3 = 0;
Random myRandomNumberObject = new Random();
int matchNum1;
int matchNum2;
int matchNum3;
//clear the list box
myListBoxResults.Items.Clear();
//set number of attempts = 0
int myAttemptsInt;
myAttemptsInt = 0;
//LOOP THROUGH AND CREATE SETS OF 3 RANDOM DIGITS EACH TIME THROUGH LOOP UNTIL A MATCH IS FOUND OR TRY 1,000 TIMES
while (myAttemptsInt <= 1000)
{
if (myAttemptsInt <= 999)
{
//ok
}
else
{
break;
}
//get next random digit generated from 0 to 9, for your generated digit position 1
random1 = myRandomNumberObject.Next(10);
//get next random digit generated from 0 to 9, for your generated digit position 2
random2 = myRandomNumberObject.Next(10);
//get next random digit generated from 0 to 9, for your generated digit position 3
random3 = myRandomNumberObject.Next(10);
//display the number of match attempts so far
//attempt # originally went here
myAttemptsInt = myAttemptsInt + 1;
int index = myListBoxResults.Items.Add("Attempt # " + myAttemptsInt);
//display the generated digit 1,2,3 in the labels on the Form
matchNum1 = random1;
myLabelGenerated1stDigit.Text = matchNum1.ToString();
matchNum2 = random2;
myLabelGenerated2ndDigit.Text = matchNum2.ToString();
matchNum3 = random3;
myLabelGenerated3rdDigit.Text = matchNum3.ToString();
//set the Label BackColor of all the generated digits to Color.LightGray
myLabelGenerated1stDigit.BackColor= Color.LightGray;
myLabelGenerated2ndDigit.BackColor = Color.LightGray;
myLabelGenerated3rdDigit.BackColor = Color.LightGray;
//for any generated digit that matches the winning digit,
if (random1 == userEntered1stDigit)
{
myLabelGenerated1stDigit.BackColor = Color.LightGreen;
}
if (random2 == userEntered2ndDigit)
{
myLabelGenerated2ndDigit.BackColor = Color.LightGreen;
}
if (random3 == userEntered3rdDigit)
{
myLabelGenerated3rdDigit.BackColor = Color.LightGreen;
}
// -keep track of the matching status of each digit in a boolean
bool doTheyMatch = true;
if (random1 = userEntered1stDigit)
//check all three boolean match variables, if they are all true then we have a match to the winning number, exit out of the while
/*
if (??)
{
//add what happened to the event log
//break out of while loop since found a match
break;
//
}
else
{
//add what happened to the event log
//no need to break out of loop; keep looping
}
*/
} // End of While
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true
或false
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
了
if(theyMatch == true)
{
//your code
}
//Behaves the same as
if(theyMatch)
{
//Your code
}
