Answer:

B

Explanation:

This question demonstrates the concept of method overloading

Method overloading means having different versions of the same method. In this case the method mystery() has three versions. The compiler is able to determine which method to call by their different parameters

The first implementation of mystery requires an array of integers as parameter

The second implementation requires an int variable

The third implementation requires a String

The Method call mystery(6 * 8) will output B because 6*8 evaluates to an integer which is the expected argument.

11111nata11111 [884]

Answer:

Following are the program to this question:

#include <iostream> //defining header file

using namespace std;

int hailstoneLength(int n) //defining method hailstoneLength

{

int t=1; //defining integer variable assign  

while(n!=1) //define a loop that checks value is not equal to 1

{

if(n%2==0) // check even number condition

{

n=n/2; // divide the value by 2 and store its remainder value in n

t++; //increment value of t by 1.

}

else

{

n=n*3+1; //calculate and hold value in n  

t++; //increment value of t variable by 1  

}

}

return t; //return value

}

int main() //defining main method

{

int n; //defining integer variable

cout<<"Enter any number: "; //print message

cin>> n; //input value

cout<<hailstoneLength(n); //call method and print its value

return 0;

}

Output:

Enter any number: 3

8

Explanation:

Program description can be given as follows:

  • In the given C++ language program an integer method "hailstoneLength", is declared, that accepts an integer variable "n" in its parameter.
  • Inside the method, an integer variable t is declared, that assign a value that is 1, in the next line, a while loop is declared, that uses if block to check even condition if number is even it divide by 2 and increment t variable value by 1.
  • If the number is odd it will multiply the value by 3 and add 1 and increment t by 1 then it will go to if block to check value again. when value of n is not equal to 1 it will return t variable value.
  • In the main method, an integer variable "n" is used that call the method and print its return value.
