要求:输入3个double实数,求出它们的和/平均值/平方和/平方和的开方,并输出。

#include 
#include
int main(){ double x, y, z,三数和,平均值,平方和,平方和开方; scanf_s("%lf %lf %lf", &x, &y, &z); 三数和 = x + y + z; 平均值 = 三数和 / 3; 平方和 = x * x + y * y + z * z; 平方和开方 = sqrt(平方和); printf("三数和 = %.2f\n平均值 = %.2f\n平方和 = %.2f\n平方和开方 = %.2f\n", 三数和, 平均值, 平方和, 平方和开方);}

输出结果:

10 20 30三数和 = 60.00平均值 = 20.00平方和 = 1400.00平方和开方 = 37.42
