如何用C语言计算矩形的周长和面积？（附代码）

#include <stdio.h>

/* height and width of a rectangle in inches */

int width;         

int height;        

int area;          

int perimeter;     

int main() {

    height = 7;

    width = 5;

    perimeter = 2*(height + width);

    printf("Perimeter of the rectangle = %d inches\n", perimeter);

    area = height * width;

    printf("Area of the rectangle = %d square inches\n", area);

return(0);

}

Perimeter of the rectangle = 24 inches                                

Area of the rectangle = 35 square inches
