不明白为什么输出的是科学计数法

Question

#include <iostream>

using namespace std;
    int Max1(int,int);
    int Max1(int,int,int);
    double Max1(double,double);
    double Max1(double,double,double);

int main()
{
    int x1,x2;
    cin>>x1>>x2;
    cout<<Max1(x1,x2)<<" ";
    int x3,x4,x5;
    cin>>x3>>x4>>x5;
    cout<<Max1(x3,x4,x5)<<" ";
    double x6,x7;
    cin>>x6>>x7;
    cout<<Max1(x6,x7)<<" ";
    double x8,x9,x0;
    cin>>x8>>x9>>x0;
    cout<<Max1(x8,x9,x0)<<" ";
    return 0;
}
int Max1(int a,int b)
{
    return a>b?a:b;
}
int Max1(int a,int b,int c)
{
    int Max1=a>b?a:b;
    return Max1>c?Max1:c;
}
double Max1(double a,double b)
{
    return a>b?a:b;
}
double Max1(double a,double b,double c)
{
    double Max1=a>b?a:b;
    return Max1>c?Max1:c;
}

输入1 2 3 1.1 2.2
理想输出 2 3 1.1 3.3

Answer 1

输入错误了，
cin>>x1>>x2;这里能正确读取到1和2
cin>>x3>>x4>>x5;这里，x3/x4/x5也是int类型，所以输入3 1.1 2.2的时候，3能正确读取，但是1.1和2.2赋值的时候就出现错误了。

把第15行的 int x3,x4,x5;改成double x3,x4,x5;
