Answer:
I am going to write the if-else statement using C++, python and JAVA
Explanation:
<h2>
// C++ code:</h2>
int main() //enters body of program
{ int points; //declare variable named points
cout<<"enter a number"; //inputs a number from user
cin>>points; //stores the input number in points variable
if(points<9 || points>51)
//if condition checks if the number in points variable is in range of 9 to 51
cout<<"invalid";
//if the number is less than 9 OR greater than 51 then it will display invalid
else
cout<<"valid"; }
// else number is in range of 9 to 51 and the output displayed is valid.
<h2>
// JAVA code</h2>
import java.util.Scanner; //scanner is used to take the user input
public class Main{
public static void main(String[] args) {
int points;
Scanner sc = new Scanner(System.in);
System.out.println("Enter a Number: "); //takes number from user
points = sc.nextInt(); //number stored in the points variable
sc.close();
if(points<9 | | points>51) //if condition to check the range
{System.out.println("invalid");}
//prints invalid when its out of range of 9 to 51
else
{System.out.println("valid");}}}
// prints valid if number in pointer variable is in the given range
<h2>
#Python code</h2>
#takes input from user
userinput=input("enter a number")
#stores input number in points variable
points = int(userinput)
#checks if the range of input number is less than 9 or greater than 51
if points<9 or points>51:
#prints invalid if the number in pointers variable is out of range of 9 to 51
print('invalid')
else:
print('valid')
# prints valid if then points variable is in the range of 9 to 51
