c语言写园的周长和面积

以下是C语言计算矩形的周长和面积的例子：

#include <stdio.h>

int main() {
    int length = 6;
    int width = 4;
    int perimeter = 2 * (length + width);
    int area = length * width;
    printf("Perimeter of the rectangle = %d inches\n", perimeter);
    printf("Area of the rectangle = %d square inches\n", area);
    return 0;
}

输出结果为：

Perimeter of the rectangle = 20 inches
Area of the rectangle = 24 square inches
