nadezda [96]

Answer:

Employing Java language,

Explanation:

//for using stack data structure

import java.util.Stack;

//class definition

public class BracketMatch {

   //function to find the string is well formed or not

   public static boolean isWellFormed(String str) {

       //variable to store the character value

       char ch;

       //check if the first character itself is the end of the brackets

       if (str.charAt(0) == ')'||str.charAt(0) =='}'||str.charAt(0) ==']')

           return false;

       //creating a stack of character type

       Stack<Character> stack = new Stack<Character>();

       //iterating through the characters in string

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

           //storing the current character from the string in the variable

           ch = str.charAt(i);

           if(ch == '('||ch=='{'||ch=='[')

               //if the character is starting of the brackets push it into stack

               stack.push(ch);

           else if(ch == ')')

               //if it is closing bracket and the stack is empty then the string is not well formatted

               if(stack.empty())

                   return false;

               else if(stack.peek() == '(')

                   stack.pop();

               else

                   return false;

           else if(ch == '}')

               if(stack.empty())

                   return false;

               else if(stack.peek() == '{')

                   stack.pop();

               else

                   return false;

       }

       //returning the stack content, if the string will be well formed the stack would be empty

       //after all the operations

       return stack.empty();

   }

   //main method

   public static void main(String[] args) {

       //calling function to find if the string is welll formatted or not

       System.out.println(isWellFormed("{}"));

       //calling function to find if the string is welll formatted or not

       System.out.println(isWellFormed("([)]"));

   }

There exists a data type Date with member function Increment that increments the current Date object by one. The ++ operator is
nalin [4]

Answer:

Date Date::operator++( int )

{

Date temp = *this;

Increment();

return temp;

}

Explanation:

Of options 1 through 4, only option 4 correctly implement the post increment of the ++ operator.

Interpreting each line of option for and comparing it to other options

Line 1: Date Date::operator++( int )

This declares the data type and its ++ operator

This is same for all options

Line 2: The Date type needs to be declared

In option 4, it was declared correctly as Date temp = *this;  using a pointer variable *this.

Here, option 2 is removed from the list of possible options.

Comparing other options

Line 3: The member increment option needs to be declared after the declaration of the date type variable.

This is correctly declared as Increment();  in option 4

Here, option 3 is removed from the list of possible options.

Comparing other options

Line 4: The value declared variable temp needs to be returned the way it was declared (without pointer indicator)

Hence, option 4 is best appropriate
