Assume the existence of a class named window with functions named close and freeresources, both of which accept no parameters an
denis-greek [22]
In your question whereas there is a class named window and it would be like this:

class window {
//code here 
}

Next is there is a function called close and freeresource and it goes like this:

class window{
  function close( ){
   //code here
  }
  function freeresource( ){
  // code here
  }
 public destruct (){
this.close();
this.freeresource();
}

}
The last code function destruct invokes the function close and freeresource. Hope this would help

Which of the following declares an abstract method in an abstract C++ class? (Points : 2) public: void print();
Dahasolnce [82]

Answer:

public: virtual void print()=0;

Explanation:

An abstract class contains a pure virtual function. Pure virtual class cannot be instantiated but it can be subclassed and the subclass can provide an implementation of the function.

A virtual function declaration in the class is preceded by the virtual keyword. For example, virtual void print();

A pure virtual function declaration is followed by '=0;'

public: virtual void print()=0;

8.11 LAB: Count characters - functions Write a program whose input is a character and a string, and whose output indicates the n
Shkiper50 [21]

Answer:

#include<iostream>

using namespace std;

int CountCharacters(char userChar, const string inputstr){

   int k = 0;

   int iter = 0;

   for (iter = 0; iter < inputstr.size(); iter++){

       if (inputstr[iter] ==  userChar){

           ++k;        }}

   return k;}

int main(){

   string str;

   char userChar[1];

   cout<<"Char: ";    cin>>userChar;

   cin.ignore();

   cout<<"String: ";   getline(cin, str);

   cout<<CountCharacters(userChar[0],str);

   return 0;}

Explanation:

Written in C++:

The function is defined here:

int CountCharacters(char userChar, const string inputstr){

This initializes a count variable k to 0

   int k = 0;

This initializes an iterating variable iter to 0

   int iter = 0;

This iterates through the characters of the string being passed to the function

   for (iter = 0; iter < inputstr.size(); iter++){

This checks for matching characters

       if (inputstr[iter] ==  userChar){

If found,  k is incremented by 1

           ++k;        }}

This returns the total count

   return k;}

The main begins here

int main(){

This declares a string variable

   string str;

This declares a character variable

   char userChar[1];

This gets input for the character variable

   cout<<"Char: ";    cin>>userChar;

This lets the user get another input

   cin.ignore();

This gets input for the string variable

   cout<<"String: ";   getline(cin, str);

This calls the function and return the count of character in the string

   cout<<CountCharacters(userChar[0],str);
