//PROJECT: Project for function overloading study, designing for 08 C++ experiments. //DATE: 2009.4.5 //AUTHOR: HHTecShare //REMARKS: This program is used to show the influence of key words "const" on function overloading. #include <iostream> using namespace std; //void constTest_1(int); //prototype of an overloading function with an integer parameter //void constTest_1(const int); //prototype of an overloading function with a const integer parameter void constTest_2(const int &); //prototype of an overloading function with a const integer reference parameter void constTest_2(int &); //prototype of an overloading function with a non-const integer reference parameter void constTest_3(const int &); //prototype of an overloading function with a const integer reference parameter void constTest_4(int &); //prototype of an overloading function with a non-const integer reference parameter void constTest_5(const int *); //prototype of an overloading function with a const integer pointer parameter void constTest_5(int *); //prototype of an overloading function with a non-const integer pointer parameter void constTest_6(const int *); //prototype of an overloading function with a const integer pointer parameter void constTest_7(int *); //prototype of an overloading function with a non-const integer pointer parameter int main() { int arg = 0; //an integer that will be used as an argument const int constArg = 0; //a const integer that will be used as an argument constTest_2(arg); //invoking with a non-const integer argument constTest_2(constArg); //invoking with a const integer argument constTest_3(arg); //invoking with a non-const integer argument //constTest_4(constArg); //invoking with a const integer argument constTest_5(&arg); //invoking with a pointer to a non-const integer argument constTest_5(&constArg); //invoking with a pointer to a const integer argument constTest_6(&arg); //invoking with a a pointer to a non-const integer argument //constTest_7(&constArg); //invoking with a a pointer to a const integer argument return 0; } //void constTest_1(int) //{ // cout << "Function \"constTest_1(int)\" is called." << endl; //} // //void constTest_1(const int) //{ // cout << "Function \"constTest_1(const int)\" is called." << endl; //} void constTest_2(const int &arg) { cout << "Function \"constTest_2(const int &)\" is called." << endl; } void constTest_2(int &arg) { cout << "Function \"constTest_2(int &)\" is called." << endl; } void constTest_3(const int &arg) { cout << "Function \"constTest_3(const int &)\" is called." << endl; } void constTest_4(int &arg) { cout << "Function \"constTest_4(int &)\" is called." << endl; } void constTest_5(const int *argPtr) { cout << "Function \"constTest_5(const int *)\" is called." << endl; } void constTest_5(int *argPtr) { cout << "Function \"constTest_5(int *)\" is called." << endl; } void constTest_6(const int *argPtr) { cout << "Function \"constTest_6(const int *)\" is called." << endl; } void constTest_7(int *argPtr) { cout << "Function \"constTest_7(int *)\" is called." << endl; }
