Write a program that Demonstrate Default Arguments in C++

Demonstrate use of Parameter Default

SoUrCe CoDe:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

#include <iostream.h> #include <conio.h> using namespace std; // Prototype Declarations void printInt (int num = 0); // Note default to 0 int main() { // Demonstrate Default Parameter cout << " Calling with no Parameter \n"; printInt (); // Demonstrate parameter value passed cout << "\n Calling with parameter 5 \n"; printInt (5); return 0; } //main /* ============= printInt ================= Print integer value pre nothing Post Either 0 or parameter value printed */ void printInt (int num) { cout << " Parameter value is: " << num << endl; getch(); return; }// printInt

OuTpUt:

 Calling with no Parameter
 Parameter value is: 0

 Calling with parameter 5 
 Parameter value is: 0
