Write a C++ program that creates an array “A” having 5 elements (in the main function). Then,

the program asks the user to enter values in this array. After that, the program should ask

question from user are you wanted to sort ascending or descending order kindly enter your

choice that’s you want to search in the array, also compute the sum of array for the ascending

order and difference of array for the descending order.

BinaryStore Calculator

A BinaryStore calculator will store bytes “stored in strings” with their addresses, i.e., at each address in the BinaryStore there is a stored Byte. Each address will be 4 characters string and each byte will be 8 characters strings.

Create a class BinaryStore and class Byte that offer following overloaded operators.

class offers the following methods:

 an overloaded +=operator that will add the address in the list of BinaryStore

 an overloaded + that will add two string bytes for Byte Class

 an overloaded - that will subtract two string bytesByte Class

 an overloaded || operator that will give the string which is bit by bit logical or of act two string bytes for Byte Class

 an overloaded && operator that will give the string which is bit by bit logical and of act two string bytesf or Byte Class

 an overloaded == operator that will give bool value if they are equal or notfor Byte Class

The program has the following structure:

• Declare three int variables nrPupils, nrGroups, and nrLeft. nrPupils represents the number of pupils in a class, nrGroups represents the number of groups the class is divided into, and nrLeft represents the number of pupils, if any, who are in the remaining smaller group.

• Assign the value 56 to nrPupils.

• Declare an int variable groupSize that is used by a cin statement to input a value from the keyboard and store the size of the groups the teacher requested. Display an appropriate message. E.g. Please enter the size of each group?

• Write the statement to calculate the number of groups of size groupSize.

• Write the statement to calculate the number of pupils who are in the remaining smaller group.

Write a function to conduct input validation to secure the smallest buffer. You may call this function void SecurePasswordBuffer(const char *arg). 

Your goal is to implement a generic “String” class using char array. Please also write down the test code to drive all functions of your class implementation

class String{

private: //think about private members

public: //give definitions of following functions

String(); -default constructor

String(char *str); -initializes string with constant cstring

String(const String &); -copy constructor

String(int x); -initialize string of pre-defined size

void setAt(int i, char c); -set character at index [x]

String substr(int pos, int len); -return substring of length len from ‘pos’

String substr(int pos); -return substring from given position to end

\void append(String str ); -append a String at end of string

void append(char *str ); -append a constant c string at end of string

char * tocstring(); -convert String to c-string

void display(); -display string

bool isEmpty(); -return true if string is empty

void copy(const String&); -copy one string to another

void copy(const char *); -copy cstring to String

};

Write a program to count and print even values between 0 and 20:

Sample Output

The Total even numbers between 0 and 20 exclusives is 10

Make a C++ program that will display the sum of the values of ingeter array with a length of 6. The values of array will be input values from the user. Use for Loops.

Make a c++ program that will display all the contents of an integers array with a length of 5. Use a for Loop.

Did you know that in lotteries, a 3-digit number with the same numbers in all digits like 777 will hit the jackpot in a casino? In the same manner, let's make a program that will test if a certain 3-digit number hits a jackpot or not by identifying if all the digits of a given number is the same as the second inputted number. If it is, print "Jackpot!"; else, print "Nah".

Let's try this out now!

Input

A line containing two integers separated by a space.

Write a C++ program that creates an array “A” having 5 elements (in the main function). Then, the

program asks the user to enter values in this array. After that, the program should replace each array

element which is divisible by 3 with new value (by adding 1 to it). In the end, the main program (“main”)

shows the updated array elements in ascending order.
