Answer:
Constant
Explanation:
A default argument is a value provided in a function declaration that the compiler automatically assigns if the function caller does not provide a default value for the argument.
The value of a default argument must be constant.
The default value parameter must be a constant for compiling. Compiler does not accept dynamically calculated value against optional parameter. The reason behind this it is not certain that the dynamic value you provide would offer some valid value.
<u>Example:</u>
#include<iostream>
using namespace std;
/*A function with default arguments, it can be called upto 4 arguments*/
int sumnum(int x, int y, int z=0, int w=0)
{
return (x + y + z + w);
}
int main() //driver function
{
cout << sumnum(10, 15) << endl;
cout << sumnum(10, 15, 25) << endl;
cout << sumnum(10, 15, 25, 30) << endl;
return 0;
}
<u>Output</u>
<u>25
</u>
<u>50
</u>
<u>80</u>

Explanation:
Automorphic Number
Given a number N, the task is to check whether the number is Automorphic number or not. A number is called Automorphic number if and only if its square ends in the same digits as the number itself.
Examples :
Input : N = 76
Output : Automorphic
Explanation: As 76*76 = 5776
Input : N = 25
Output : Automorphic
As 25*25 = 625
Input : N = 7
Output : Not Automorphic
As 7*7 = 49
