一个求数组中最大元素的函数模板

#include<iostream>#include<cstdio>using namespace std;template<class T>T MaxElement(T a[], int size){T temMax = a[0];for (int i = 1; i < size; ++i){if (temMax < a[i]){temMax = a[i];}}return temMax;}class CFraction{private:int numerator;int denominator;public:CFraction(int n, int m) :numerator(n), denominator(m){}bool operator <(const CFraction & s);friend ostream & operator <<(ostream & os, const CFraction& s);};bool CFraction::operator<(const CFraction& s){return (this->numerator)*(s.denominator) < (this->denominator)*(s.numerator);}ostream & operator << (ostream & os, const CFraction& s){os << s.numerator << "/" << s.denominator << endl;return os;}int main(){int a[5] = { 1, 5, 2, 3, 4 };CFraction f[4] = { CFraction(8, 6), CFraction(8, 4), CFraction(3, 2), CFraction(5, 6) };cout << MaxElement(a, 5) << endl;cout << MaxElement(f, 4) << endl;system("pause");return 0;}
