函数的重载
#include<iostream>
using namespace std;
int min(int a,int n){
int m,i=0;
while(i>=n-1){
if(a[i]<a[i+1])
{
a[i+1]=a[i];
m=a[i+1];
}
i++;
};
return m;
}
double min(double a,int n){
double m;
int i=0;
while(i>=n-1){
if(a[i]<a[i+1])
{
a[i+1]=a[i];
m=a[i+1];
}
i++;
};
return m;
}
float min(float a,int n){
float m;
int i=0;
while(i>=n-1){
if(a[i]<a[i+1])
{
a[i+1]=a[i];
m=a[i+1];
}
i++;
};
return m;
}
long min(long a,int n){
long m;
int i=0;
while(i>=n-1){
if(a[i]<a[i+1])
{
a[i+1]=a[i];
m=a[i+1];
}
i++;
};
return m;
}
void main()
{
int a[3]={1,2,3};
double b[3]={1.14546,2.165465,3.1654};
float c[3]={1.1,2.2,3.3};
long d[3]={1,2,3};
cout << min(a,3) << endl;
cout << min(b,3) << endl;
cout << min(c,3) << endl;
cout << min(d,3);
}
然后出现了一大堆错误

[解决办法]
函数参数写错了
int min(int a,int n)
你这样写的a是整型的，不是数组
正确写法
int min(int*a ,int n)
