### Rational Number or Rational Mothod in ruby or rational operation

Rational Number or Rational Mothod in ruby or Rational operation Rational Number is always comes with paired integer Number(1 ,2 ,3 .... && -1, -2, .....) x/y (where y>0). Rational (1) => (1/1) Rational (2, 5) =>(2/5) Rational(4, -8) => (-1/2) 5.to_r =>(5/1) 2/3r => (2/3) Rational into Numeric rational*numeric -> numeric (perfoms multiplecation) Rational(1, 3)  * Rational(2, 3)   => (2/9) Rational(200)   * Rational(1)      => (200/1) Rational(-5, 4) * Rational(-4, 5)  => (1/1) Rational(9, 4)  * 4                => (9/1) Rational(20, 9) * 9.8              => 21.77777777777778 rat ** numeric => numeric (Performs exponentiation) Rational(3)    ** Rational(3)    => (27/1) Rational(10)   ** -2             => (1/100) Rational(10)   ** -2.0           => 0.01 Rational(-4)   ** Rational(1,2)  => (1.2246063538223773e-16+2.0i) Rational(1, 2) ** 0              => (1/1) Rational(2,

### Fibonacci series without using recursion?

#include<stdio.h> #include<conio.h> void printFibonacci(int n){ static int n1=0,n2=1,n3; if(n>0){ n3 = n1 + n2; n1 = n2; n2 = n3; printf("%d ",n3); printFibonacci(n-1); } } void main(){ int n; clrscr(); printf("Enter the number of elements: "); scanf("%d",&n); printf("Fibonacci Series: "); printf("%d %d ",0,1); printFibonacci(n-2); //n-2 because 2 numbers are already printed getch(); } Enter the number of elements : 15 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
