In a Fortran program, if I have set x=2.0,a=2.0, b=4.0, what is the value of y. If y=a*x+b**2/x?

Question 1

A sequence is a database/schema object used to generate a unique auto-number. The auto-number generated through a sequence is independent of tables, which means that the same number can be used for multiple tables. 

Consider the following table: 

Assignment_No  Course_Code   Total_Marks 

1  CS201  15 

2  CS614  20 

1  CS614  10 

5  CS610  25 

3  CS409  15 

 You are required to write a PL/SQL PROCEDURE named Add that insert a new record in the above table

Create a Sequence named Supplier_Seq which generate an auto-number for the Supplier_ID column of the following table. 

Supplier_ID  Supplier_Name  Contact_No  Country_Name 

Note: The sequence should start with the number 202, each sequence number must be even, for faster access, the CACHE value should be 20 and there should be no cycle in the sequence. 

Write a program that declared a class with one integer data member and two member functions for input data and output data. Decide appropriate access modifiers for these members. Use this class in your program.

Define a class TEST in C++ with following description:Private MembersTestCode of type integerDescription of type stringNoCandidate of type integerCenterReqd (number of centers required) of type integerA member function CALCNTR() to calculate and return the number of centers as(NoCandidates/100+1)Public Members - A function SCHEDULE() to allow user to enter values for TestCode, Description, NoCandidate & call function CALCNTR() to calculate the number of Centres- A function DISPTEST() to allow user to view the content of all the data members  

"cin.ignore();" what type of cin statement is this and how it is used in a program?

Define a class batsman with the following specifications:Private members:bcode 4 digits code numberbname 20 charactersinnings, notout, runs integer typebatavg it is calculated according to the formula  batavg =runs/(innings-notout)calcavg() Function to compute batavgPublic members:readdata() Function to accept value from bcode, name, innings,   notout and invoke the function calcavg()displaydata() Function to display the data members on the screen.  

Build an algorithm to parse and process the dynamic expression based on the dictionary

provided. The expression basically consists of Operators, Variables, and Parentheses.

Parentheses have higher precedence (i.e the subexpression in the parentheses should be

executed first)

Basically, the algorithm should support two operators - AND (concatenates the two variables) &

OR (provides first variable value if it is available. Otherwise, go for the second variable)

The algorithm should parse the given expression and apply the respective dictionary values on

the expression and provides the respective computed results.

Program to convert a given number to Dollar format

Write code to convert a given number into dollar format. For example, if “1234567” is

given as input, the output should be “one million two hundred thirty-four thousand

five hundred sixty-seven dollars”. Code should be able to provide output up to 1

billion.
