使用C++，定义多个简单函数完成直角三角形，等腰三角形，矩形，平行四边形，菱形的输出

在C++中，你可以定义一系列函数来分别处理这五种图形的输出。这里是一个简单的示例，每个函数接收相应的属性作为输入并打印出图形：

#include <iostream>

// 直角三角形
void print_right_triangle(int side) {
    for (int i = 0; i <= side; ++i) {
        std::cout << "* ";
        for (int j = 0; j < side - i; ++j)
            std::cout << "  ";
        std::cout << "\n";
    }
}

// 等腰三角形
void print_isosceles_triangle(int base, int height) {
    for (int i = 0; i < base; ++i) {
        if (i == 0 || i == base / 2) {
            std::cout << "#";
        } else {
            std::cout << " ";
        }
        for (int j = 0; j < height - 1; ++j) {
            std::cout << " ";
        }
        std::cout << "#\n";
    }
}

// 矩形
void print_rectangle(int width, int height) {
    for (int i = 0; i < height; ++i) {
        for (int j = 0; j < width; ++j)
            std::cout << "* ";
        std::cout << "\n";
    }
}

// 平行四边形
void print_parallelogram(int base, int side) {
    for (int i = 0; i < base; ++i) {
        for (int j = 0; j < side; ++j)
            std::cout << "* ";
        if (i % 2 == 0)
            std::cout << "\n";
        else
            std::cout << "\t";
    }
}

// 菱形
void print_kite(int length, int width) {
    for (int i = 0; i < length; ++i) {
        if (i == 0 || i == length / 2)
            std::cout << "* ";
        else if (i % 2 == 0)
            std::cout << " ";
        for (int j = 0; j < width; ++j) {
            if (j == 0 || j == width / 2)
                std::cout << "* ";
            else
                std::cout << " ";
        }
        std::cout << "\n";
    }
}

// 打印帮助信息
void print_usage() {
    std::cout << "Usage: Call a function with appropriate parameters like print_right_triangle(side)\n";
}

int main() {
    // 示例调用
    print_right_triangle(5);
    print_isosceles_triangle(6, 4);
    print_rectangle(4, 3);
    print_parallelogram(5, 3);
    print_kite(7, 4);

    return 0;
}
