create a running database  C++ program.

Can add, search, or delete a record.

Write a function called sum, that calculates the total value of a and b, where a and b are integers, a= 100 and b = 200 in the main function. Your main function will declare your variables, call the function to add values and then call the function again. When you compile your program it has to give you total result of sum (a, b) from the main function, and the result for sum (a,b) from the function sum. There is a default value of b which is part of the function list, with the value 20. Your function sum, will calculate the result of a and b, and then return the result.

Write a program to find the winner of each round of game based on the shape of players chose

Create a program that will make the user input the Month, Date and Year as Integers then use switch statemet and concatenation to display it in this format:

Sample output

Month : 6

Day : 13

Year : 2022

June 13, 2022

Note: If the user inputs an invalid Month then you should tell the user that it is invalid by using the default keyword.

Syntax of default keyword is default:

Input names into a list. The user will be asked if he wants to add another name or not in the list

Output:

Enter your name: Jose, Dela Cruz

Jose

Dela Cruz

Add Another name: Yes

Enter your name: Juan, Cruz

Juan

Cruz

Add Another Name: No

Stop the program

a=9

b=100

write a program to find a number of perfect squares a to b

Write a C++ function that determines in which quadrant a line

drawn from the origin resides. The determination of the quadrant

is made using the angle that the line makes with the positive x

axis as follows:

Note: if the angle is exactly 0,90,180,270 degrees the

corresponding line does not reside in any quadrant but lies on an

axis.

Angle from the

positive x axis Quadrant

Between 0 and 90 degrees =1

Between 90 and 180 degrees =2

Between 180 and 270 degrees =3

Between 270 and 360 degrees = 4

Write a C++ program to read and print details of N students. (Note Modify Question number 2)

a. Hints

i. Create a class to hold all student attributes, a method which interact with a user and read student details, method to print/write student details.

ii. Create a main function which will prompt a user to inter N student (Number of students to read and write their details), call function from a class above to read and write student detail.

iii. The user interactive screen and output should appear Sample output
