C++ examples for template:template function
Using a function template
#include <iostream> template <typename T> T larger(T a, T b); // Function template prototype int main()// w w w.ja v a 2 s . c om { std::cout << "Larger of 1.5 and 2.5 is " << larger(1.5, 2.5) << std::endl; std::cout << "Larger of 3.5 and 4.5 is " << larger(3.5, 4.5) << std::endl; int a_int {35}, b_int {45}; std::cout << "Larger of " << a_int << " and " << b_int << " is " << larger(a_int, b_int) << std::endl; long a_long {9L}, b_long {8L}; std::cout << "Larger of " << a_long << " and " << b_long << " is " << larger(a_long, b_long) << std::endl; } // Template for functions to return the larger of two values template <typename T> T larger(T a, T b) { return a > b ? a : b; }
