C Program to Display Fibonacci Series Using While Loop: Fibonacci series is a series of numbers in which each number of the Fibonacci series is derived by the adding of its two immediate preceding numbers.Fibonacci sequence is one of the most famous formulas in mathematics.

C Program to Display Fibonacci Series Using While Loop

#include<stdio.h>
int main()
{
    int n,i,a,b,c;
    printf("Enter a Number: ");
    scanf("%d",&n);
    i=1;
    a=0;
    b=1;
    while(i<=n)
    {
        printf("%d ",a);
        c = a + b;
        a = b;
        b = c;
        i++;
    }
    return 0;
}
