Answer:
The program to this question can be given as follows:
Program:
//class
public class factorial //defining class
{
//method fact
public static long fact(int x1) //defining method fact
{
//conditional statement
if (x1 <= 1) //if block checks parameter value less then equal to 1
{
return 1; //return value
}
else //else part
{
return (fact(x1 - 1) * (long) x1); //return factors using recursive function
}
}
//method main
public static void main(String[] args) //defining main method
{
long data=fact(5);//defining variable that holds function value
System.out.println("Factorial is: "+data); //print value
}
}
Output:
Factorial is: 120
Explanation:
In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.
- If the block it checks parameter value is less then equal to 1, if this condition is true, it will return 1 when this condition is not true. It will go in else part.
- In else part, it uses a recursive function to calculate factorial of a number and return its value.
- Then the main method is defined, inside this method a long variable "data" is defined, that call and holds fact function return value, and in the next line, the print function is used to print the data variable value.
Answer:
I did not understand a thing from your writing
Answer:
It can deliver the services faster with higher reliability and quality
Answer:
command line and graphical user interface
Explanation:
there were (and still are) operating system with no graphical user interface at all, as for example some Unix releases
Answer:
count = 0
while count != 8:
height = float(input("Enter height of the rider: "))
if height >= 140:
print("You are allowed to ride")
count += 1
else:
if height >= 120:
answer = input("Is the rider with an adult (yes/no): ")
if answer == "yes":
print("You are allowed to ride")
count += 1
else:
print("You are not allowed to ride")
else:
print("You are not allowed to ride")
Explanation:
Initialize the count as 0, it will count the number of people allowed to ride
Create a while loop that iterates while count is not equal to 8
Inside the loop, ask the user for the height. If the height is greater than or equal to 140, print "You are allowed to ride" and increment the count by 1. Otherwise, check if the height is greater than or equal to 120. If it is not, print "You are not allowed to ride". If it is, ask if the rider is with an adult or not. If it is not, print "You are not allowed to ride". If it is print "You are allowed to ride" and increment the count by 1.
