Write a C++ program that reads the number of sales (as integer values) at the end of each month for the ABC Supermarket of 5 departments (grocery, bakery, meat, vegetables, and electronics). The program reads all data from the input file sales.txt. The first line has an integer value N that represents the number of months to be processed. The following N input lines contain the name of the month followed by the sales of each department in that month (5 integer values).
Your program shall produce a nice report in a file report.txt showing the list of months and the sum of 5 sales for that month. The program will also output the total sum of all sales and the average sales per month. Format your output to produce an exact result as in the sample below. To output the # use setw(3), to output the month name use setw(6) and use setw(12) to output the sum of sales for the month. The final output should be limited to 2 decimal places.
Write a base class Computer that contains data members of wordsize(in bits),
memorysize (in megabytes), storagesize (in megabytes) and speed (in megahertz).
Derive a Laptop class that is a kind of computer but also specifies the object’s length,
width, height, and weight. Member functions for both classes should include a default
constructor, a constructor to inialize all components and a function to display data
members.
Write a class Person that has attributes of id, name and address. It has a constructor to
initialize, a member function to input and a member function to display data members.
Create another class Student that inherits Person class. It has additional attributes of
rollnumber and marks. It also has member function to input and display its data
members.
Write a program having a base class Student with data members rollno, name and
Class define a member functions getdata() to input values and another function
putdata() to display all values. A class Test is derived from class Student with data
members T1marks, T2marks, T3marks, Sessional1, Sessional2, Assignment and Final.
Also make a function getmarks() to enter marks for all variables except Final and also
make a function putmarks() to display result. Make a function Finalresult() to
calculate value for final variable using other marks. Then display the student result
along with student data.
write a program executing a loop,which is readinginteger numbers from the keyboard until at least one of the below listed conditions is fulfilled
1.the multiplication of these numbers exceeds 1000
2.the number of reported even numbers exceeds 10
3.three subsequent numbers will have exactly the same value (eg 3,4,2,5,5,5)
char secretCode(int n){
char letters[ ]= "abcdefghijklmnopqrstuvwxyz";
int number = n;
while (number >26){
number = number - 26;
}
return letters[number-1];
}
The code above runs perfectly well,
1. what would be the return value if the argument value for parameter n is 243?
2. what would be the return value if the argument value for parameter n is 123?
3. what would be the return value if the argument value for parameter n is 12456?
4. what would be the return value if the argument value for parameter n is 345?
5. what would be the return value if the argument value for parameter n is 354?
6. what would be the return value if the argument value for parameter n is 456?

The cost of a brand new car is P420,000 for GL model and P398,000 for XL model. If a car
phone will be installed, an additional P40,000 will be added to the cost. Moreover, a 15%
discount on the total cost will be given if the buyer pays in full (not installment).
Write a program that would input the car model bought whether with car phone (use code
"W" for car with car phone and "O" for without car phone) and whether it will be paid in full (use
code "F" for full payment and "I" for installment). Program must then output the net cost of the
car.
In order to discourage excess electric consumption, an electrical company charges its customers a lower rate of P75 for the first 250 kilowatt-hours and a higher rate of P85 for each additional kilowatt-hour. In addition, a 10% surtax is added to the final bill. Write a program that calculates the electrical bill given the number of kilowatt-hours consumed as input. At the end, print the number of kilowatt-hours consumed and the computed bill.
