Problem Description
编写重载函数min()，分别计算int、double、float、long类型数组中的最小值。 程序如下，请完善该程序的设计：
#include <iostream> using namespace std; int min(int [],int); double min(double[],int); float min(float[],int); long min(long[],int); int main(){ int a[6]={2,22,0,-6,67,-111}; int aa[4]={5,19,2,28}; double b[8]={2.2,62,-6.1,500,68.2,-500.345,-8,1000}; float c[4]={3.2,-8.61,699,33}; long d[3]={3265891,14789,-63256}; cout<<"the least number in a[6] is "<<min(a,6)<<endl; cout<<"the least number in b[8] is "<<min(b,8)<<endl; cout<<"the least number in c[4] is "<<min(c,4)<<endl; cout<<"the least number in d[3] is "<<min(d,3)<<endl; cout<<"the least number in aa[4] is "<<min(aa,4)<<endl; return 0; } //你的代码将被嵌在这里Sample Output
the least number in a[6] is -111 the least number in b[8] is -500.345 the least number in c[4] is -8.61 the least number in d[3] is -63256 the least number in aa[4] is 2解题代码
