C 语言查找菱形面积的程序

编写一个 C 语言程序，通过示例查找菱形的面积。计算菱形面积的数学公式是（对角线1 * 对角线2）/2。此示例允许输入第一条和第二条对角线，并返回菱形的面积。

#include <stdio.h>

int main()
{
    float rmD1, rmD2, rmArea;
    
    printf("Enter the Rhombus First diagonal = ");
    scanf("%f",&rmD1);

    printf("Enter the Rhombus Second diagonal = ");
    scanf("%f",&rmD2);

    rmArea = (rmD1 * rmD2)/2;

    printf("The Area of a Rhombus = %.2f\n", rmArea); 
    
    return 0;
}

使用函数查找菱形面积的程序。

#include <stdio.h>

float rhombusArea(float rmD1, float rmD2)
{
    return (rmD1 * rmD2)/2;
}
int main()
{
    float rmD1, rmD2, rmArea;
    
    printf("Enter the First diagonal = ");
    scanf("%f",&rmD1);

    printf("Enter the Second diagonal = ");
    scanf("%f",&rmD2);

    rmArea = rhombusArea(rmD1, rmD2);

    printf("The Area = %.2f\n", rmArea);
    
    return 0;
}

Enter the First diagonal = 11
Enter the Second diagonal = 17
The Area = 93.50
