平方和

#include <iostream>
using namespace std;

//请在这里编写两个sumOfSquare函数
int sumOfSquare(int m,int n)
{
    return m*m+n*n;
    
      
    
}
double sumOfSquare(double m,double n)
{
    
    return m*m+n*n;
    
    
}
int main(){
    int m, n;
    cout << "请输入两个整数：";
    cin >> m >> n;
    cout << "整数的平方和是：" << sumOfSquare(m, n) << endl;
    double x, y;
    cout << "请输入两个实数：";
    cin >> x >> y;
    cout << "实数的平方和是：" << sumOfSquare(x, y) << endl;
    return 0;
}

#include<iostream>
#include<iomanip>
using namespace std;

    cout << getVolume(X,Y,Z) << endl;
  
    cout << getVolume(X, Y) << endl;
 
    cout << getVolume(X) << endl;
    system("pause");
    return 0;
}

int getVolume(int length, int width, int height)

    return h;
}

int main(){
    double r= 3.0;
    double area = calArea(r);
    cout << area << endl;
    return 0;
