Golang 如何找到平行四边形的面积

在本教程中，我们将看到在Golang中找到平行四边形的面积的程序。面积是由任何闭合图形覆盖的总空间。

Golang 如何找到平行四边形的面积

公式

Area of the Parallelogram - base * height
b - length of the base of a Parallelogram
h - length of the height of a Parallelogram

如例如何，一个平行四边形的底边长为6厘米，高为4厘米，所以平行四边形的面积为−

b = 6 cm
h = 4 cm
Area = base * height
   = 6 * 4
   = 24 cm^2

在函数中找到平行四边形的面积

步骤

步骤1 - 使用float64数据类型声明底边长度、高度长度和面积的变量。

步骤2 - 初始化变量。

步骤3 - 在函数中使用上述公式计算面积。

步骤4 - 打印结果。

Time Complexity:
O(1)

Space Complexity:
O(1)

示例1

在这个示例中，我们将在函数内找到一个平行四边形的面积。

package main
// fmt package provides the function to print anything
import (
   "fmt"
)
func main() {
   // declaring the floating variables using the var keyword for
   // storing the length of the base of the Parallelogram,
   // length of the height of the Parallelogram and also
   // a variable area to store Area
   var base, height, Area float64
   fmt.Println("Program to find the Area of a Parallelogram.")

   // initializing the length of the base of a Parallelogram
   base = 6

   // initializing the length of the height of a Parallelogram
   height = 4

   // finding the Area of a Parallelogram
   Area = height * base

   // printing the result
   fmt.Println("The Area of a Parallelogram with base =", base,"and height =", height, "is", Area, "cm * cm.")
   fmt.Println("(Finding the Area of a Parallelogram within the function)")
}

输出

Program to find the Area of a Parallelogram.
The Area of a Parallelogram with base = 6 and height = 4 is 24 cm * cm.
(Finding the Area of a Parallelogram within the function)

在独立函数中寻找平行四边形的面积

步骤

第一步 - 声明基的长度、高度的长度和浮点型面积的变量。

第二步 - 初始化变量。

第三步 - 调用函数，传入平行四边形的基的长度和高度的长度，并存储函数返回的面积。

第四步 - 打印结果。

示例2

在这个示例中，我们通过定义独立函数来找到平行四边形的面积。

package main
// fmt package provides the function to print anything
import (
   "fmt"
)
// in this line we have declared the function that have float64
// type parameter and float64 type returntype
func areaOfParallelogram(base, height float64) float64 {
   // returning the area by applying the formula
   return base * height
}
func main() {
   // declaring the floating variables using the var keyword for
   // storing the length of the base of the Parallelogram,
   // length of the height of the Parallelogram and also
   // a variable area to store Area
   var base, height, Area float64
   fmt.Println("Program to find the Area of a Parallelogram.")

   // initializing the length of the base of a Parallelogram
   base = 6

   // initializing the length of the height of a Parallelogram
   height = 4

   // finding the Area of a Parallelogram by calling the
   // function with the respective parameters
   Area = areaOfParallelogram(base, height)

   // printing the result
   fmt.Println("The Area of a Parallelogram with base =", base,"and height =", height, "is", Area, "cm * cm.")
   fmt.Println("(Finding the Area of a Parallelogram in the separate function)")
}

输出

Program to find the Area of a Parallelogram.
The Area of a Parallelogram with base = 6 and height = 4 is 24 cm * cm.
(Finding the Area of a Parallelogram in the separate function)
