C++ examples for Function:Function Overload
Outputs three different types of data with overloaded function.
#include <iostream> using namespace std; #include <iomanip> void output(char []); void output(int i); void output(float x); void main()/* w w w . ja va2 s .c o m*/ { char name[] = "this is a test!"; int ivalue = 2; float fvalue = 9.4321; output(name); output(ivalue); output(fvalue); return; } void output(char name[]) { cout << setw(30) << name << "\n"; return; } void output(int ivalue) { cout << setw(5) << ivalue << "\n"; // printed integer within a width of five spaces. return; } void output(float fvalue) { cout << setprecision(2) << fvalue << "\n"; // Limited the floating-point value to two decimal places. return; }
