Question1:
What is the output of the following program?
#include <iostream>
using namespace std;
//prototype of function find
void find (int &a, int &b, int c);
int main ()
{
int one, two, three;
one = 1;
two = 2;
three = 3;
//call function find
find (one, two, three);
cout << "first call: " << one << ", " << two << ", " << three << endl;
//call function find
find (one, two, three);
cout << "second call: " << one << ", " << two << ", " << three << endl;
//call function find
find (one, two, three);
cout << "third call: " << one << ", " << two << ", " << three << endl;
system("pause");
return 0;

}
//User defined function with reference parameters
void find (int &a, int &b, int c)
{
int temp;
c = a + b + 1 ;
temp = c + 2;
a = a + c;
b = a + temp;
}
Solution
Answer 1:
output is
Answer 2:
in the definition of the function
void functionDefaultParam(double x = 2.4, int y = 3, string z = "H")
the string is not a defined datatype in c++, you can use array of character
