编写重载函数min（），分别计算int，double，float，long类型数组中的最小数

#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];}i++;};m=a[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];}i++;};m=a[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];}i++;};m=a[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];}i++;};m=a[i];return m;}void main(){int a[3]={1,2,3};double b[3]={1.1,2.1,3.1};float c[3]={2.1,2.3,2.4};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) << endl;}

如果使用模版函数的话会简单很多。。。

#include<iostream>using namespace std;template<class T,class T1>T min(T* a,T1 n){int m,i=0;while(i<n-1){if(a[i]<a[i+1]){a[i+1]=a[i];}i++;};return a[i];}void main(){int a[3]={1,2,3};double b[3]={1.1,2.1,3.1};float c[3]={2.1,2.3,2.4};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) << endl;}
