ifstream file("text.txt");

 

  //cheks whether given file is present or not

  if(!file){

      cout<<"File not Found";

      return 0;

  }

  //variables for all three counts and character in file

char character;

int uppercaseCount=0, lowercaseCount=0, digitsCount=0;

  //loop for reading and checkile file character by character

while(file){

      //get a single character

file.get(character);

 

      //checks uppercase character

if((character >= 'A') && (character <= 'Z'))

uppercaseCount++;

     

      //checks lowercase character

 else if((character >= 'a') && (character <= 'z'))

lowercaseCount++;

     //checks lowercase character

      else if((character >= '0') && (character <= '9'))

      digitsCount++;

}

cout<<"\nUppercase characters: "<<uppercaseCount;

cout<<"\nLowercase characters: "<<lowercaseCount;

cout<<"\nDigits: "<<digitsCount;

return 0;

If myClass has a constructor with a parameter of type String, select the other constructor that should be included.
JulijaS [17]

Answer:

d. public myClass( ) {. . .}

Explanation:

A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.

Having said these about a constructor, a few other things are worth to be noted by a constructor.

i. In Java, a constructor has the same name as the name of its class.

For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.

ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:

<em>public void myClass(){...}</em>

This makes option a incorrect.

iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts  of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.

This makes option d a correct option.

Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.

Write a java program to read elements in an array from user and count total number of duplicate elements in array.
Anna11 [10]

Answer:

Explanation:

The following code is written in Java and is a function/method that takes in an int array as a parameter. The type of array can be changed. The function then creates a counter and loops through each element in the array comparing each one, whenever one element is found to be a duplicate it increases the counter by 1 and moves on to the next element in the array. Finally, it prints out the number of duplicates.

public static int countDuplicate (int[] arr) {

               int count = 0;

               for(int i = 0; i < arr.length; i++) {

                       for(int j = i + 1; j < arr.length; j++) {

                               if(arr[i] == arr[j])

                                       count++;

                       }

               }

               return count;

       }
