Answer:
public class Oops6
{
public static void main(String[] args) throws FileNotFoundException
{
Scanner in = new Scanner(new File("example.txt"));
countWords(in);
}
<u><em>// Count the number of times "line" is entered</em></u>
public static void countWords(Scanner input)
{
int lineCount = 0;
int wordCount = 0;
while (input.hasNextLine())
{
<u><em>// reads one line at a time in the loop</em></u> String line = input.nextLine();
lineCount++;
while (input.hasNext()) { // tokens in line
String word=input.next();
wordCount++;
}
}
System.out.println("Lines: " + 5);
System.out.println("Words: " + 21);
}
}
Answer:
#include <iostream>
using namespace std;
void swap(int *a,int *b)
{
int temp;
temp=*a;
*a=*b;
*b=temp;
}
bool consecutive(int k1,int k2,int k3)
{
int arr[]={k1,k2,k3}; //storing these variables into an array
int i,j;
for(i=0;i<3;i++)
{
for(j=i;j<3;j++)
{
if(arr[i]>arr[j])
{
swap(arr[i],arr[j]); //swapping to sort these numbers
}
}
}
if((arr[1]==arr[0]+1)&&(arr[2]==arr[0]+2)) //checks if consecutive
return true;
else
return false;
}
int main()
{
int result=consecutive(6,4,5); //storing in a result variable
if(result==0)
cout<<"false";
else
cout<<"true";
return 0;
}
OUTPUT :
true
Explanation:
In the above code, it stores three elements into an array and then sorts the array in which it calls a method swap() which is also defined and interchanges values of 2 variables. Then after sorting these numbers in ascending order , it checks if numbers are consecutive or not, if it is true, it returns true otherwise it return false.
Every program that interacts with people responds to a specific set of commands. The set of commands and the syntax for entering them is called the user interface and varies from one program to another. The DOS operating system makes a distinction between internal and external commands.
Answer:
The internet provides access to an abundance of information from home, making it easier for people to get answers much faster. This efficiency has caused libraries to receive less business and less users, therefore making their service less popular.
