Answer:
Following are the program in the Python Programming Language:
def check(num): #define function
if(num.isdigit()): #set if statement
return "yes"; #return yes if condition is true
else:
return "no";# return no if condition is false
string=input("Enter the numbers 0-9: ") #get input from the user
print(check(string)) #print and call the function
Output:
Enter the numbers 0-9: 1995
yes
Enter the numbers 0-9: 42,000
no
Explanation:
Here, we define a function "check()" and pass an argument in its parameter "num" inside the function.
- we set if-else conditional statement and check the value stored in the variable "num" is the digit by using built in function "isdigit()" then return "yes".
- Then, otherwise it return "no".
Finally, we get the input from the user in the variable "string" then, we call the function through "print()" function.
Answer:
"backdoor" is the correct answer for the above question
Explanation:
- The backdoor is a type of attack which is done by the type of backdoor programs to remotely access the computers without the authorization of the user of the computer.
- It is inserted on the computer with the help of the internet and accessed the computer without using authorization techniques.

Answer: d. should be lowercase.
Explanation:
ID attributes are case sensitive for the most part - DOM and Java Script - which means that the ID attribute does not always have to be lowercase.
It can be uppercase as well. ID attributes can also start with a number and as of HTML 5 can start with a special character as well. Finally, the ID attribute must always be unique within each document.
Answer:
#include <iostream>
using namespace std;
void swap(int& m, int& n) /* passing by reference so that changes will be made in the original values.*/
{
int t=m;
m=n;
n=t;
}
int main()
{
int val1,val2;
cout<<"Enter the values"<<endl;
cin>>val1>>val2;
cout<<"Values before swap "<<val1<<" "<<val2<<endl;
swap(val1,val2);
//calling the function swap..
cout<<"Values after swap "<<val1<<" "<<val2<<endl;
return 0;
}
Explanation:
Created a function swap with 2 arguments m and n passed by reference.
It allows commonly used instructions to be stored for easier access, but the ram gets deleted when ever you restart the computer.
