def CountVowels(epsilon):

   countNum = 0

   for x in range(len(epsilon)):

       letter = epsilon[x]

       if letter.lower() in "aeiou":

           countNum += 1

   return countNum

def ExtractOdds(zeta):

   result = ""

   for x in range(len(zeta)):

       if x % 2 == 1:

           result += zeta[x]

   return result

sentence_A = input("Enter a sentence: ")

sentence_B = input("Enter a sentence: ")

print(CountVowels(sentence_A))

print(ExtractOdds(sentence_B))

I hope this helps!

Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to beco
Alex787 [66]

Answer:

One of the strategies to avoid nested conditional is to use logical expressions such as the use of AND & operator.

One strategy is to use an  interface class with a method. That method can be created to be used for a common functionality or purpose. This is also called strategy design pattern. You can move the chunk of conditional statement to that method. Then each class can implement that interface class and use that shared method according to their own required task by creating objects of sub classes and call that common method for any such object. This is called polymorphism.

Explanation:

Nested conditionals refers to the use of if or else if statement inside another if or else if statement or you can simply say a condition inside another condition. For example:

if( condition1) {  

//executes when condition1 evaluates to true

  if(condition2) {

//executes when condition1  and condition2 evaluate to true

  }  else if(condition3) {

 //when condition1 is true and condition3 is true

} else {

 //condition1  is true but neither condition2 nor conditions3 are true

}  }

The deeply nested conditionals make the program difficult to understand or read if the nested conditionals are not indented properly. Also the debugging gets difficult when the program has a lot of nested conditionals.

So in order to avoid nested conditionals some strategies are used such as using a switch statement.

Here i will give an example of the strategies i have mentioned in the answer.

Using Logical Expressions:

A strategy to avoid nested conditionals is to use logical expressions with logical operators such as AND operator. The above described example of nested conditionals can be written as:

if(condition1 && condition2){  //this executes only when both condition1 and condition2 are true

} else if(condition1 && condition3) {

this executes only when both condition1 and condition3 are true

} else if(condition1 ){

//condition1  is true but neither condtion2 nor condtion3 are true  }

This can further be modified to one conditional as:

if(!condition3){

// when  condition1 and condition2 are true

}

else

// condition3 is true

Now lets take a simple example of deciding to go to school or not based on some conditions.

if (temperature< 40)

{

   if (busArrived=="yes")

   {

       if (!sick)

       {

           if (homework=="done")

           {

               printf("Go to school.");

           }

       }                    

   }

}

This uses nested conditionals. This can be changed to a single conditional using AND logical operator.

if ((temperature <40) && (busArrived=="yes") &&

(!sick) && (homework=="done"))

{    cout<<"Eligible for promotion."; }

The second strategy is to use an interface. For example you can

abstract class Shape{

//declare a method common to all sub classes

  abstract public int area();

// same method that varies by formula of area for different shapes

}

class Triangle extends Shape{

  public int area() {

     // version of area code for Triangle

return (width * height / 2);

  }

}

class Rectangle extends Shape{

  public int area() {

     // version of area code for Rectangle

    return (width * height)

  }

}

// Now simply create Rectangle or Triangle objects and call area() for any such object and the relevant version will be executed.

}

}

public class KantoPokemonException extends PokemonException {

public KantoPokemonException() {

super();

}

}

public class JohtoPokemonException extends PokemonException {

public JohtoPokemonException() {

}

}

public class UnovaPokemonException extends PokemonException {

public UnovaPokemonException() {

super();

}

}

public class KalosPokemonException extends PokemonException {

public KalosPokemonException() {

super();

}

}

public class AlolaPokemonException extends PokemonException {

public AlolaPokemonException() {

super();

}

}

public class GalarPokemonException extends PokemonException {

public GalarPokemonException() {

super();

}

}

Explanation:

  • A separate Java file needs to be created for each of the following exception.
  • Inside the constructor, call the super() method to inherit all the properties of a parent class.

Misha Larkins [42]

Answer:

The correct answer to the following question will be "Flash memory card".

Explanation:

A flash memory card seems to be a storage (small) medium which stores data or information on fordable or remote devices using non-volatile transistor technology hardware.

  • Most newer offerings include flash storage or memory chips, even though the development of other memory innovations is underway.
  • This would be the storage mechanism from which the configuration tool was replicated by Thomas' friend.
