Answer:
Following are the code to this question:
#include <iostream> //defining header file
using namespace std;
void numbers(ostream &outs, const string& prefix, unsigned int levels); // method declaration
void numbers(ostream &outs, const string& prefix, unsigned int levels) //defining method number
{
string s; //defining string variable
if(levels == 0) //defining condition statement that check levels value is equal to 0
{
outs << prefix << endl; //use value
}
else //define else part
{
for(char c = '1'; c <= '9'; c++) //define loop that calls numbers method
{
s = prefix + c + '.'; // holding value in s variable
numbers(outs, s, levels-1); //call method numbers
}
}
}
int main() //defining main method
{
numbers(cout, "THERBLIG", 2); //call method numbers method that accepts value
return 0;
}

Explanation:
Program description:
- In the given program, a method number is declared, that accepts three arguments in its parameter that are "outs, prefix, levels", and all the variable uses the address operator to hold its value.
- Inside the method a conditional statement is used in which string variable s and a conditional statement is used, in if the block it checks level variable value is equal to 0. if it is false it will go to else block that uses the loop to call method.
- In the main method we call the number method and pass the value in its parameter.
Answer:
Even though both are interfaces and serve its purpose of attempting to run the strategies, their components as well as the manipulate they will get from the patient differ.
Explanation:
CUI (Character User Interface) :-
- It's a sort of user interface that only uses binary data and pseudographics for interface-output and data sessions.
- That's characterized by low availability for operating systems I / O resources (act with integrity) and high speed with a display of data.
GUI (Graphical User Interface (GUI):-
- Using graphical elements such as windows, icons, menus helps the user to communicate with the program.
- It is a kind of user interface along which people interact with electronic equipment through characterizations of visual indicators.
A barcode's bars have
1. different thicknesses, so they each signify 1 or 2 nibbles.
2. the combinations of the thicknesses of those bars exceed the trillions. That's why manufacturers and stores never run out of SKU barcodes.
