如何在Golang中检查三个布尔变量中的两个是否为真
在本教程中,我们将在Golang中三个布尔变量中的两个是真还是假。因为只有三个变量,所以可以用 if else
条件语句来检查。
使用 if
、 elsei
f和 else
条件语句进行检查。
算法
第1步 – 声明布尔变量,在后面进行比较。
第2步 – 用各自的值初始化变量。
第3步 – 使用 if elseif
和 else
梯子比较变量。
例子1
在这个例子中,将用if、elseif和else条件语句进行检查。
package main
// fmt package provides the function to print anything
import (
"fmt"\n)
func main() {
// declaring the three variables that
// we have see are true or not
var numberOne, numberTwo, numberThree bool
// initializing the variables
numberOne = true
numberTwo = false
numberThree = true
fmt.Println("Number one =",numberOne,"nNumber Two =",numberTwo,"nNumber Three=",numberThree)
// using the if else if ladder we are checking all three
// possibilities where two variables can be true if not
// then we are having else condition to handle that
if numberOne == true && numberTwo == true && numberThree == false {
fmt.Println("Two of three variables are true.")
} else if numberOne == true && numberTwo == false && numberThree == true {
fmt.Println("Two of three variables are true.")
} else if numberOne == false && numberTwo == true && numberThree == true {
fmt.Println("Two of three variables are true.")
} else {
fmt.Println("Two of three variables are not true.")
}
}
运行结果:
Number one = true
Number Two = false
Number Three = true
Two of three variables are true.
只用if条件语句进行检查

示例2
在这个例子中,将只用if条件语句来检查。
package main
// fmt package provides the function to print anything
import (
"fmt"\n)
func main() {
// declaring the three variables that
// we have see are true or not
var numberOne, numberTwo, numberThree bool
// declaring and initializing the count variable which will
// store the count of the variables that are true
var count int
count = 0
// initializing the variables
numberOne = true
numberTwo = false
numberThree = false
fmt.Println("Number one =",numberOne,"nNumber Two =",numberTwo,"nNumber Three =",numberThree)
// using the if condition to check the
// first variable is true or not
if numberOne == true {
count++
}
// using the if condition to check the
// second variable is true or not
if numberTwo == true {
count++
}
// using the if condition to check the
// third variable is true or not
if numberThree == true {
count++
}
// checking the count is two or not
if count == 2 {
fmt.Println("Two of three variables are true.")
} else {
fmt.Println("Two of three variables are not true.")
}
}
运行结果:
Number one = true
Number Two = false
Number Three = false
Two of three variables are not true.
