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;
}
Output:

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:
Code is completed below
Explanation:
Source Code in Java:
class Parenthesis
{
boolean hasBalancedParentheses(String eq) //method to check and return if a set of parenthesis is balanced or not
{
int count=0; //to store count of current unclosed opening brackets
for(int i=0;i<eq.length();i++)
{
if(eq.charAt(i)=='(')
count++;
else if(eq.charAt(i)==')')
count--;
if(count<0) //if count falls below zero, there were more closing brackets than opening brackets till this point
return false;
}
if(count>0) //if count is still more than zero, there were less closing brackets than opening brackets
return false;
return true; //if program reaches this point, it has passed all the tests
}
public static void main(String args[])
{
//testing the function
Parenthesis ob=new Parenthesis();
System.out.println(ob.hasBalancedParentheses("()(()())((())())"));
System.out.println(ob.hasBalancedParentheses(")((()())(()))())"));
}
}
Answer:
A transmission line that consists of a tube of electrically conducting material surrounding a central conductor held in place by insulators and that is used to transmit telegraph, telephone, television, and Internet signals.
Coax, short for coaxial, is a type of cable used to transmit data, the internet, video and voice communications. A coax cable is made up of an aluminum and copper shield with an outer plastic jacket (see below) with the dielectric insulator helping to minimize signal loss.
