Answer:

Class are the collection of variable and member function.

Class are the blueprint of an object.

Explanation:

Following are the points regarding class in c++

1.In C++ class is an user defined datatype..

2.Classes are the collection of variable and function in c++.

3.To access the property of class we can create object of that class

4.We can use following syntax to declared any class in c++

class classname

{

accessmodifier:

//statement and function

};

main()

{

classname objectname;

}

implementation of class in c++

#include<iostream>

class test // class declaration

{

public: // access modifier

void fun3() // Method definition

{

cout<<" hello :";

}

};

void main() // main function

{

test ob;// creating object

ob.fun3(); // calling function

}

In this program we declared a class "test " in class test. We giving public access modifier .The public access modifier define that variable and function are accessible outside the class and in main method we create the object ob which call the function fun3().

Output:hello :

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in

Zina [86]

Answer:

Here is the C++ program:

#include <iostream> // to include input output functions

using namespace std; // to identify objects like cin cout

int counter(string userString, char character) { //function counter

int count = 0; // counts the no of times a character appears in the string

for (int i=0;i<userString.length();i++)

// loop to move through the string to find the occurrence of the character

if (userString[i] == character) //if characters is found in the string

count++; //counts the occurrence of the character in the string

return count; } //returns the no of times character occurs in the string

int main() { //start of the main() function body

string s; // stores the string entered by the user

cout<<"Enter a string: "; //prompts user to enter the string

cin>>s; //reads the string from user

char ch; //stores the character entered by the user

cout<<"Enter a character: "; //prompts user to enter a character

cin>>ch; //reads the character from user

cout << counter(s, ch) << endl; }

//calls counter function to find the number of times a character occurs in the //string

Explanation:

The counter function works as following:

It has a count variable which stores the number of occurrences of a character in the userString.

It uses a for loop which loops through the entire string.

It has i position variable which starts with the first character of the string and checks if the first character of userString matches with the required character.

If it matches the character then count variable counts the first occurrence of the character and in the userString and is incremented to 1.

If the character does not match with the first character of the userString then the loops keeps traversing through the userString until the end of the userString is reached which is specified by the length() function which returns the length of the string.

After the loop ends the return count statement is used to return the number of occurrences of the character in the userString.

The main() function prompts the user to enter a string and a character. It then calls counter() function passing string s and character ch arguments to it in order to get the number of times ch appears in s.

The output is attached in a screenshot.

Security Risk Scoring

Proprietary Risk Assessment relays the security posture of an organization's databases at-a-glance through risk scores.

Operational Security

Discovers and mitigates internal and external threats in real time through Database Activity Monitoring plus alerting and reporting. Identifies and tracks behavior while looking for anomalous activity internally and externally.

Database Activity Monitoring

Monitors 1 to 1,000+ databases simultaneously, synthesizing internal and external activity into a unified console.

Only by covering both of these areas can organizations have defense in depth and effectively control risk.

frutty [35]

Answer:

B. False

Explanation:

Consumption of alcohol is not a good practice and is generally not allowed at the time of driving an automobile and is considered to be an offense as it may be injurious to health and property.

As too much alcohol can create possible chances of collusions and even if the person is not in an automobile can result in a collision if tries to cross the road. Like head injuries or leg injuries can occur.

The instruction format of a computer is given by one indirect bit, opcode bits, register address bits, immediate operand bits an

oksian1 [2.3K]

Answer:

Following are the answer to this question:

Explanation:

The memory size is 1 Giga Bytes which is equal to $2^{30}$

$\texttt{Number of address bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ Number of addresses}\\\\ \ \ \ \ 30 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2^{30}= 1073741824$

B) $\texttt{I \ \ \ Opcode \ \ \ Register address \ \ \ Immediate operand \ \ \ Memory address}\\\\\\\textt{1 \ bit \ \ \ \ \ \ 128 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2 \ bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 24 \ bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 30 \ bits}\\\\\\$ $= 2^7 \\\\ = 7 \ bits$

calculating the register Bits:

$= 64-(1+7+24+30)\\\\=64 -62\ \ bits\\\\= 2\ \ bits\\$

Immediate value size while merging the additional benefit with the address field:

$= 2^{24} + 2^{30}\\\\= 2^{54}\\\\$ $\texttt{Range before combining(-,+) 24 bits \ \ \ \ \ \ Range after combining( -,+)54bits}\\\\$ $\textt{-2^{12} from + (2^{12}-1) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -2^{27} from + (2^{27}- 1)}$

$= \frac{24}{2} = 12\\\\= \frac{54}{2} = 27$

The range is accomplished by dividing the bits by 2 into the two sides of the o and the number is one short to 0.
