Alogarithm steps:

1. Start the program
2. Write one function with default arguments
3. Call that function in the main program
4. The function be called without arguments, with single arguments, with two arguments
5. Compile and run the program.

CPP Program for Functions With Default Arguments

#include void f(int a=0, int b=0) { cout << "a: " << a << " b: " << b; cout << '\n'; } int main() { f (); f (10); f(10, 99); return 0; }
