14 The default value of parameter in specified in 15 Passin

14. The default value of parameter is specified in..? A. Function call B. Function definition Function prototype D. Both B or O 15. Passing arguments by reference is declared using the symbol below:

Solution

Question 14:

the default value MUST be in the function prototype and not in the function implementation.

example :

int Add(int a, int b = 3);

so answer c is correct

Question 15:

Answer is : B

sample program :

#include <iostream>

using namespace std;

void changeI(int* i);
int main()
{
int i = 5;
cout << \"Before passing \" << i << endl;
changeI(&i);
cout << \"after passing \" << i << endl;
return 0;
}
// change i
void changeI(int* i)
{
*i = 34;
}

Output:

Before passing 5                                                                                                                       

after passing 34
