Answer:

The output is "A"

Explanation:

public class Solution {

   public static void main(String args[]) {

     mystery(7);

   }    

   public static void mystery(int a) { System.out.println("A"); }    

   public static void mystery(double a) { System.out.println("B"); }    

   public static void mystery(int a, double b) { System.out.println("C"); }    

   public static void mystery(double a, int b) { System.out.println("D"); }

}

In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.

In the first case; mystery will be called if the argument is int.

In the second case; mystery will be called if the argument is double.

In the third case; mystery will be called if the arguments are int and double.

In the fourth case; mystery will be called if the arguments are double and int.

When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".

zalisa [80]

Answer:

#include <iostream>

#include <cstdlib>

using namespace std;

int main() {

   int[] array = new int[10];

   int index = 0;

   while(index < array.size()){

           int number = (rand() % 100) + 1;

           for (int i = 0; i < 1; i++) {

               array[index] = number;

               cout<< "Position "<< index << "of the array = "<< number << endl;

               ++index;

           }

     }

}

Explanation:

The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.
