Question

Using print(), loops, conditionals, and classes write a script that outputs a Fibonacci sequence (every number after the first two is the sum of the two preceding ones): 1, 1, 2, 3, 5, 8, 13,

Answer 1

i am writing it in java:

//printing fibonocci upto given number
public class Main
{
   public static void main(String[] args) {
   Main a = new Main();//creating object for main clss
       a.generate_fibonocci(5);//call the function objectname.funcname
   }
//method calculate fibonocci number
public void generate_fibonocci(int number)
{
//initializing first two fibonocci numbers 0,1
int first = 0, second = 1, next;
//if given number greater than 0, print first fibonocci number
if (number >= 0)
System.out.print( first + " ");
//if given number greater than 1, print second fibonocci numb
if (number >= 1)
System.out.print( second + " ");
//for loop 2 to given number
for (int i = 2; i <= number; i++)
{
next = first + second; //adding two previous numbers to get next fibonocci
System.out.print( next + " ");
first = second; //override the previous lst value into first and new value(next) into second
second = next;
}
}
}

output:

explanation:

we have initially taken first two fibonocci numbers because next fibonocci is sum of previous two.

if we give n=5,it gives the all fibonocci upto 5.

for example:

first=0

second = 1

next fibonocci will be (0+1) = 1

next fibonocci:

store the second value in first and new fibonocci in second. add them to get fourth number.

repeat it.

note: if you want this program in language, let me know, I will write and send u in comment box.
