Answer Posted / ambar
A space allocated for a particular item of information. A
tax form, for example, contains a number of fields: one for
your name, one for your Social Security number, one for
your income, and so on. In database systems, fields are the
smallest units of information you can access. In
spreadsheets, fields are called cells
Record
In database management systems, a complete set of
information. Records are composed of fields, each of which
contains one item of information. A set of records
constitutes a file. For example, a personnel file might
contain records that have three fields: a name field, an
address field, and a phone number field
Table
Refers to data arranged in rows and columns. A spreadsheet,
for example, is a table. In relational database management
systems, all information is stored in the form of tables.
Data Base
A collection of information organized in such a way that a
computer program can quickly select desired pieces of data.
You can think of a database as an electronic filing system.

If P is the population on the first day of the year, B is the birth rate, and D is the death rate, the estimated population at the end of the year is given by the formula: The population growth rate is given by the formula: B – D Write a program that prompts the user to enter the starting population, birth and death rates, and n, the number of years. The program should then calculate and print the estimated population after n years. Your program must have at least the following functions: 1. growthRate: This function takes its parameters the birth and death rates, and it returns the population growth rate. 2. estimatedPopulation: This function takes its parameters the current population, population growth rate, and n, the number of years. It returns the estimated population after n years Your program should not accept a negative birth rate, negative death rate, or a population less than 2. please answer my question ....
a program using one dimensional array that searches a number if it is found on the list of given input numbers given by the user and locate its exact location in the list.
