Write a program to take input for n number of employee records and write records of all employees in a file named: “record1”. Also write records of all those employees in another file named: “record2” who are taking salary more than 50,000. After writing records in both files, merge their contents in another file: “finalrecord” and read all records of “finalrecord” file and display on screen. [Attributes of employee: emp_id, emp_name, emp_experience, emp_salary]
Write a C++program to accept two integers and check if it is greater than or equal to 100. If not, return a message "The number is less than 100". Specify the input of first and second of the possible output.
Create a Class Shape having a field shapeType and a function printMyType.Create another class, Square and Rectangle, which inherits the Shape class and has additional fields length and breadth. Both Square and Rectangle classes will have two functions calculateArea, which will return the object's area, and printMyType, which will print the type of the object.Inside the main, first create the object of class Square and have a length equal to 5 and call the printMyType then calculateArea method after creating the object of class Rectangle having the length equal to 5 and breadth equal to 4 and again call the printMyType and calculateArea method.
Considering the Abstraction Principle, perform the following:
a. [2 Marks] Define an abstract class by the name of Shape, the class consists of an attribute (D) which refers to the dimension and a member function Area().
b. [2 Marks] Make the function Area a pure virtual function
c. [2 Marks] Define a class Circle which is s subclass of the superclass Shape and define the Area inside the class.
d. [1 Marks] Define a second class Square which is a subclass of Shape and define the area inside it.
Given a linked list containing n nodes. The problem is to insert a new node
with data x at the middle of the list. If n is even, then insert the new node
after the (n/2)th node, else insert the new node after the (n+1)/2th node
Suppose we have a pointer to float data type which contains the memory address
value 100.
If we add the integer value 3 to this pointer, what will be the value of the pointer if float data
types are 4 bytes in length?
Write a C++ program that takes up to 10-digit integer input from user (can be 1 digit, 2 digit, and so on..); passes this to a function which reverses the digits. Finally, the reversed number should be displayed in the main function. For example: when user enters 10-digit like 1234567890 your function will reverse it to 987654321. Do not use strings. Be careful for big integer values. [use functions, decision control]
A number is called a happy number, if you start with the given number
and arrive at 1 by repeating the following process (as illustrated in the below example):
(a) compute the sum of the squares of given number digits
(b) if the resultant value is 1, then the number is happy number, else execute point (a) for
the newly produced number.
Note that if a number is not a happy number, there will be an endless loop to this execution.
Goal: In this question, you are required to write a recursive function that checks whether
the number entered by the user is a happy number or not for 10 cycles/iterations only. The
output shown in blue colour should be shown by the function and text in yellow colour
should be displayed by the main function.
a. Write a function convert() that converts a decimal number to a binary, octal, and
hexadecimal equivalents. The function will take two arguments: first argument will be
the number to be converted and second argument will be the base in which this number
is to be converted. Function should return the converted value. You may use strings to
represent converted numbers like “0x3A”, “00101100”, “72” etc. Lower limit must be smaller than upper limit.
b. Call convert() function in the main program to produce the following output.
Example output:
Enter upper limit = 20
Enter lower limit = 10
