两种不同写法取最小数组元素

// o414.cpp : Defines the entry point for the console application. // #include "stdafx.h" using namespace std; template <class Type,int size> Type getMin(Type (&array)[size]) { Type minVal = array[0]; for (int i=0;i<size;i++) { if (array[i]<minVal) { minVal = array[i]; } } return minVal; } template <class Type> Type getMin2(Type *array,int size) { Type minVal = array[0]; for (int i=0;i<size;i++) { if (array[i]<minVal) { minVal = array[i]; } } return minVal; } template <class Type> Type getMin3(const Type *array,int size) { Type minVal = array[0]; for (int i=0;i<size;i++) { if (array[i]<minVal) { minVal = array[i]; } } return minVal; } template <class Type> Type myMax(Type a,Type b) { return a>b?a:b; } int _tmain(int argc, _TCHAR* argv[]) { double myd[] = {0.3,1,2,2.2,4,8}; cout<<getMin(myd)<<endl; cout<<getMin2(myd,sizeof(myd)/sizeof(double))<<endl; cout<<getMin3(myd,sizeof(myd)/sizeof(double))<<endl; //cout<<myMax(3,8)<<endl; system("pause"); return 0; }
