Program Plan Intro
Program Plan:
- Insert required header Files
- Create new file PhoneNumber.h.
- Make a class PhoneNumber and declare extraction and insertion operators as friend to class.
- Declare three string variable “ areacode ”, “ exchange ”, “ line ” and one character array “ phno ” to get phone number in an array.
- End header class.
- Close and save header file.
- Create new file Phonenumber.cpp. This will contain definitions and modification required in extraction operator ">>".
- Include header files, must include PhoneNumber.h
- Overload the insertion operator to display areacode, exchange and line.
- Make changes the extraction operator definition.
- use "getline()" function to get input into "phno". The "getline()" function is used to identify psaces also.
- Use if construct to check various conditions
- Check for length of input entered which should be 14, use input.clear(ios::failbit) to set failbit.
- Check that areacode does not start with either 0 or 1, if it does then use input.clear(ios::failbit) to set failbit.
- Check that exchange does not start with either 0 or 1, if it does then use input.clear(ios::failbit) to set failbit.
- Check that middle digit of areacode should be either 0 or 1, if not then use input.clear(ios::failbit) to set failbit.
- If all the conditions are false, this means that input is correct, thus put them into areacode, exchange and line of number object passed through the function.
- return input
- end function
- Make new C++ file for main() function.
- Include header files, must include PhoneNumber.h.
- Start main function.
- Declare an object of PhoneNumber class phone.
- Display message to enter phone number.
- Use cin>>phone which will call overloaded extraction operator.
- Check whether state returned is goodbit(incase failbit is not set in the function) then display phone number else display error.
- Return and exit.
Program Description:
Program to get correct input by overloading extraction operator.

Write a function validSolution/ValidateSolution/valid_solution()that accepts a 2D array representing a Sudoku board, and returns trueif it is a valid solution, or false otherwise. The cells of the sudokuboard may also contain 0's, which will represent empty cells.Boards containing one or more zeroes are considered to be invalid solutions.The board is always 9 cells by 9 cells, and every cell only contains integersfrom 0 to 9.

Is it correct to say that a function that accepts an array as a parameter has access to the original array or that it just has access to a copy of it?
c) Write a version of enqueue that checks for a full array. If the array is full, the function simply
returns false. If the array is not full, the behaviour is the same as the original enqueue,
except that the function also returns true.

(ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks.

- Question: Given an array of integers, find the maximum and minimum elements present in the array. Your task is to write a function that takes an array of integers as input and returns the maximum and minimum elements as a pair of integers..arrow_forwardImplement a function that finds the number of values that are less than 0 and the number of values greater than 0 stored in an array of integers. Assume the array is the partially filled array from the previous question, and uses 0 to indicate the end of values stored in it. (18 pts) Note: the results should be passed back to the caller, not directly displayed in the function. Also note, as the following code template requires, the function’s return type is void. Please finish the function header, and function implementation. Hint.. In the beginning, set the lessThan and greaterThan values to be 0. Then as you scan through the array elements one by one, compare the next array element with 0. If the element is greater, update your greaterThan count; otherwise, if the element is less, update the lessThan count, otherwise do nothing. Continue until you see the value 0.
