What is an organized collection of integrated tables called?A database is an organized collection of integrated and related tables that are designed to store, manage, and retrieve data efficiently. It serves as a structured repository where data is stored in a systematic manner, allowing for easy access, manipulation, and analysis.
A database is typically designed based on a specific data model, such as the relational model ,where data is organized into tables with predefined relationships between them. Each table represents a distinct entity or concept, and the columns of the table represent the attributes or properties of that entity. The rows of the table, also known as records or tuples, contain the actual data.
A well-designed database ensures data integrity, consistency, and security. It allows for efficient data storage and retrieval through the use of indexing, querying, and data manipulation operations. Database management systems (DBMS) are software applications that provide the tools and functionalities to create, modify, and manage databases. They handle tasks such as data storage, data retrieval, data security, and data backup.
Overall, a database provides a structured and organized approach to storing and managing data, enabling efficient data management and analysis for various applications and industries.

Which of the following expressions evaluate to 3.5 2
I (double) 2 / 4 + 3 II (double) (2 / 4) + 3 III (double) (2 / 4 + 3) A I only
B Ill only C I and II only D II and III only
E I,II, and III
The expression that evaluates to 3.5 is option A, I only.
To understand why, we need to follow the order of operations. In option I, we first divide 2 by 4, which gives us 0.5. Then we double that, which gives us 1. Finally, we add 3 to 1, which gives us 4. Option II first divides 2 by 4, which again gives us 0.5.
However, before doubling that, we add 3 to it, which gives us 3.5 when we finally double it. Option III looks similar to II, but we have to remember that division comes before addition, so we first add 2/4 and 3, which gives us 3.5. Then we double that, which gives us 7.
Therefore, the correct option is 3.5 is option A, I only.

(Debug) The following program was written to correct the error produced by the program in Exercise 11. Determine why this program also doesn’t provide the correct result and correct the error.
#include
using namespace std:
int main()
{
int num1=15;
int num2=18;
int total;
double average;
total = num1+num2;
average = total/2;
cout << "The average of" << num1
<< "and" << num2 << "is"
<< average << end1;
return 0:
}
There are a few errors in the provided program. Here is the corrected version:
#include <iostream>
using namespace std;
int main()
{
int num1 = 15;
int num2 = 18;
int total;
double average;
total = num1 + num2;
average = static_cast<double>(total) / 2; // Cast total to double for accurate division
cout << "The average of " << num1
<< " and " << num2 << " is "
<< average << endl; // Corrected the typo from "end1" to "endl"
return 0;
}
Errors corrected in the code:
The line using namespace std: has a colon: at the end instead of a semicolon; It should be using namespace std;The output statement is missing a space before "and" in the output message.The end1 at the end of the output statement should be endl to insert a new line after printing.To calculate the average accurately, the total variable should be cast to a double before division to ensure a floating-point division is performed.With these corrections, the program should provide the correct result.
