/* * average.cc - an example average program using templates * */ #include<iostream> using namespace std; template <class T> void myaverage (T val1, T val2, T val3) { T result; result = val1 + val2 + val3; cout << "First value is: " << val1 << endl; cout << "Second value is: " << val2 << endl; cout << "Third value is: " << val3 << endl; cout << "The sum of all three are: " << result << endl; cout << "The average of all three are: " << (T)(result/3) << endl; } int main() { myaverage(3.1, 7.3, 1.7); myaverage(2, 4, 6); myaverage('~', '|', 'z'); return 0; }
