Answer:
#include <iostream>
#include <cstring>
using namespace std;
struct Data {
int userId;
char name[80];
}
void newData(string data char[]){
int counts= 0;
struct Data name;
data.userId = ++counts;
data.name = char[];
cout<< data.userId << "\n"<< data.name ;
}
int main( ) {
char myName;
string mydata;
cin>> myName;
cin>> mydata;
newData( myName, mydata);
}
Explanation:
The c++ source code above stores its data in a struct called "Data". The function newData dynamically creates new data from the struct defined.
A database has one physical schema and one conceptual (logical) schema but many external schemas (views).
a) True
b) False
Answer:
true
Explanation:
A database has one physical schema and one conceptual (logical) schema but many external schemas (views): a. True.
A database refers to a structured (organized) collection of data that are stored on a computer system and usually accessed in various ways such as electronically.
In database management, a database schema can be defined as a structure which is typically used to represent the logical design of the database. Thus, it denotes how data are stored (organized) and the relationships existing in a database management system (DBMS).
Generally, there are two (2) main types of a database schema and these include;
Physical database schema: it is only one per database.Conceptual (logical) schema: it is only one per database.However, there are multiple number of external schemas (views) for each database because it is what an end user is interested in.

Allison is writing a program in Java and keeps getting an error. Which line of code is causing the error?
A. Int a = 0, b = 3, c;
B. for(i = 0, i <= 13, i++) {
C. c = (a * 2) + i;
D. System.out.println(c);
}
B will cause an error.
Allison needs to declare a type for variable i and use semi-colons.
The for statement should be for(int i = 0; i <=13; i++){
Write a script that inputs a line of plaintext and a distance value and outputs an encrypted text using a Caesar cipher.
The script should work for any printable characters. An example of the program input and output is shown below:
Enter a message: Hello world!
Enter the distance value: 4
Output: Lipps${svph%
Answer:
def encrypt_text(text,value):
encoded = ""
for i in range(len(text)):
char = text[i]
if (char.isupper()):
encoded += chr"po"ord'po'char'pc' + value -65'pc' % 26 + 65'pc'
else:
encoded += chr'po'ord'po'char'pc' + value -97'pc' % 26 + 97'pc'
return encoded
plaintext = input("Enter sentence of encrypt: ")
dist_value = int(input("Enter number: "))
encrypted = encrypt_text(plaintext, dist_value)
print(encrypted)
Explanation:
The python program above is a Ceasar cipher implementation. The encrypt_text function is defined to accept text input and a distance value, which is used to encrypt the plaintext.
The user can directly input text and the distance value from the prompt and get the encrypted text printed on the screen.
