编程面积计算器可以使用多种编程语言实现,以下是几种不同编程语言的面积计算器示例代码:

Python

```python

计算矩形的面积

def calculate_rectangle_area(length, width):

return length * width

计算圆形的面积

def calculate_circle_area(radius):

return 3.14 * (radius 2)

计算三角形的面积

def calculate_triangle_area(base, height):

return 0.5 * base * height

主程序

if __name__ == "__main__":

print("欢迎使用面积计算器!")

print("1. 矩形")

print("2. 圆形")

print("3. 三角形")

choice = int(input("请选择要计算的图形(1/2/3): "))

if choice == 1:

length = float(input("请输入矩形的长度: "))

width = float(input("请输入矩形的宽度: "))

area = calculate_rectangle_area(length, width)

print("矩形的面积为: ", area)

elif choice == 2:

radius = float(input("请输入圆形的半径: "))

area = calculate_circle_area(radius)

print("圆形的面积为: ", area)

elif choice == 3:

base = float(input("请输入三角形的底: "))

height = float(input("请输入三角形的高: "))

area = calculate_triangle_area(base, height)

print("三角形的面积为: ", area)

```

C++

```cpp

include

using namespace std;

int area(int, int);

int area(int, int, int);

int main() {

int i, repeat, c, x, y, z;

cin >> repeat;

for (i = 0; i > c; if (c == 2)) {

cin >> x >> y;

cout << x >> y >> z;

cout << area(x, y, z) << endl;

}

return 0;

}

int area(int x, int y) {

int s;

s = x * y;

return s;

}

int area(int x, int y, int z) {

int s;

s = (x * y + x * z + y * z) * 2;

return s;

}

```

Excel VBA

```vba

Sub CalculateArea()

Dim List1(1 To 100) As Double

Dim List2(1 To 100) As Double

Dim List3(1 To 100) As Double

Dim i As Integer

Dim a, b, r, s As Double

i = 1

While List1(i) <> 0

List1(i) = InputBox("请输入多边形各转折点坐标,以顺时针顺序排列,输入0结束:")

i = i + 1

Wend

i = 1

While i <= UBound(List1)

List2(i) = InputBox("请输入与List1对应的多边形各边的长度:")

i = i + 1

Wend

i = 1

While i <= UBound(List1)

List3(i) = 0

i = i + 1

Wend

i = 1

While i <= UBound(List1)

List3(i) = (List1(i) * List2(i + 1) - List1(i) * List2(i)) + List3(i)

i = i + 1

Wend

s = 0

i = 1

While i <= UBound(List1)

s = s + List3(i)

i = i + 1

Wend

s = s / 2

MsgBox "多边形的面积为: " & s

End Sub

```
