Mariulka [41]

Answer:

#include <bits/stdc++.h>

using namespace std;

void funct(){

   string name;

   cout<<"enter the string: ";

   cin>>name;

   

    reverse(name.begin(), name.end());

    cout<<"The string is : "<<name<<endl;

   

}

int main()

{

   funct();

 

  return 0;

}

Explanation:

create the function funct() with return type void and declare the variable type string and print a message for asking to used enter the string.  

The string enter by user is store in the variable using cin instruction.

after that, we use a inbuilt function reverse() which takes two argument.

firs argument tell the starting point and second index tell the ending point. then, the reverse function reverse the string.

name.begin() it is a function which return the pointer of first character of string.

name.end()  it is a function which return the pointer of last character of the string.

finally, print the reverse string.

for calling the function, we have to create the main function and then call the function.

A security team has downloaded a public database of the largest collection of password dumps on the Internet. This collection co
Scorpion4ik [409]

Answer:

a. Password length, password encryption, password complexity

Explanation:

Under this scenario, the best combination would be Password length, password encryption, password complexity. This is because the main security problem is with the user's passwords. Increasing the password length and password complexity makes it nearly impossible for individuals to simply guess the password and gain access, while also making it extremely difficult and time consuming for hackers to use software to discover the password as well. Password excryption would be an extra layer of security as it encrypts the password before storing it into the database, therefore preventing eavesdroppers from seeing the password and leaked info from being used without decryption.

Programming challenge description: Write a program that, given two binary numbers represented as strings, prints their sum in bi
Lubov Fominskaja [6]

Answer:

The program to this question can be given as:

Program:

#include<iostream>  //include header file

using namespace std;  

string add(string a, string b)  //define add function

{       //declare variable  

   string result = "";  

   int sum = 0,k,l;      

   cahr x;    

   k= a.size() - 1;

   l = b.size() - 1;  

   while (k>= 0 || l>= 0 || sum == 1) //loop

   {

   //addition 

       sum= sum+ ((k >= 0)? a[k] - '0': 0);  

       sum= sum+ ((l >= 0)? b[l] - '0': 0);

        x=sum%2;

      result=(x+'0') +result;

  // Compute carry

       sum =sum/ 2;  

       // Move to next digits  

       k--;  

       l--;  

   }  

   return result; //return value

}

int main()  //main method  

{  

   string a,b;  //string variable

   cout<<"Enter first binary digit: ";  //message.

   cin>>a;     //input from user

   cout<<"Enter Second binary digit: ";  //message.

   cin>>b;     //input from user

   cout <<"Addition :"<<add(a, b)<<endl; //print addition

   return 0;  

}

Output:

Enter first binary digit: 1101

Enter Second binary digit: 100

Addition :10001

Explanation:

In the above c++ program first, we include the header file. Then we define the add function in the add function we add two binary digits by passing value as arguments. In this function, we define a variable that is used on the addition of binary numbers. In this function we define the loop in the loop we check if two binary number is 1 then it will print 0 and pass 1 as the carry. after performing addition it will return value. In the main function, we take two binary numbers from the user and pass the value to the function and print function return value.

What are some tasks for which you can use the VBA Editor? i need help for my computer class.
Murljashka [212]

Answer:

Visual Basic for Applications runs as an internal programming language in Microsoft Office applications such as Access, Excel, PowerPoint, Publisher, Word, and Visio. VBA allows users to customize beyond what is normally available with MS Office host applications by manipulating graphical-user-interface (GUI) features such as toolbars and menus, dialogue boxes, and forms. You may use VBA to create user-defined functions (UDFs), access Windows application programming interfaces (APIs), and automate specific computer processes and calculations. Macros can automate just about any task—like generating customized charts and reports, and performing word- and data-processing functions. Programmers,like replicating large pieces of code, merging existing program functions, and designing specific languages. VBA can also work in non-Microsoft settings by using a technology called "COM interface," which allows commands to interact across computer boundaries. Many firms have implemented VBA within their own applications, both proprietary and commercial, including AutoCAD, ArcGIS, CATIA, Corel, raw, and SolidWorks.
