3.29 LAB: Login name Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: JordaM91 Ex: If the input is: Kanye West 2024 the output is: Your login name: WestK24

In C++:

#include <iostream>

using namespace std;

int main(){

   string fname,lname; int num;

   cout<<"Firstname: "; cin>>fname;

   cout<<"Lastname: "; cin>>lname;

   cout<<"4 digits: "; cin>>num;

   string login = lname;

   if(lname.length()>=5){

       login = lname.substr(0, 5);    }

   login+=fname.substr(0,1)+to_string(num%100);

   cout<<login;

   return 0;

}

See attachment for explanation where I used comments to explain each line

sory but complete the question

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
