#include <iostream> using namespace std; template <class atype> //function template atype avg(atype* array, int size) { atype total = 0;//from www.j av a2 s .c o m for(int j=0; j<size; j++) //average the array total += array[j]; return (atype)total/size; } int intArray[] = {1, 3, 5, 9, 11, 13}; long longArray[] = {1, 3, 5, 9, 11, 13}; double doubleArray[] = {1.0, 3.0, 5.0, 9.0, 11.0, 13.0}; char charArray[] = {1, 3, 5, 9, 11, 13}; int main() { cout << "\navg(intArray)=" << avg(intArray, 6); cout << "\navg(longArray)=" << avg(longArray, 6); cout << "\navg(doubleArray)=" << avg(doubleArray, 6); cout << "\navg(charArray)=" << (int)avg(charArray, 6) << endl; return 0; }
