C Program to Display Fibonacci Series

The Fibonacci Sequence is the series of numbers:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...

• The next number is found by adding up the two numbers before it.
• The 2 is found by adding the two numbers before it (1+1)
• Similarly, the 3 is found by adding the two numbers before it (1+2),
• And the 5 is (2+3),
• and so on!

#include<stdio.h>

#include<conio.h>

int n1=0,n2=1,t,i,n;

void main()

{

    printf("Enter How many numbers you want to display: ");

    scanf("%d",&n);

    printf("%d\t%d\t",n1,n2);

    for(i=1;i<=n-2;i++)

    {

        t=n1+n2;

        printf("%d\t",t);

        n1=n2;

        n2=t;

    }

getch();

}
