C++ examples for Function:Function Overload
Overloading a function with reference parameters
#include <iostream> double larger(double a, double b); // Non-reference parameters long& larger(long& a, long& b); // lvalue reference parameters int main() {/*from w w w. jav a 2s . com*/ double a_double {1.5}, b_double {2.5}; std::cout << "The larger of double values " << a_double << " and " << b_double << " is " << larger(a_double, b_double) << std::endl; int a_int {15}, b_int {25}; std::cout << "The larger of int values " << a_int << " and " << b_int << " is " << larger(static_cast<long>(a_int), static_cast<long>(b_int)) << std::endl; } // Returns the larger of two floating point values double larger(double a, double b) { std::cout << "double larger() called." << std::endl; return a > b ? a : b; } // Returns the larger of two long references long& larger(long& a, long& b) { std::cout << "long ref larger() called" << std::endl; return a>b ? a : b; }
