Write a program in C to display the sequence of Fibonacci numbers of first n numbers entered by the user.

How to display Fibonacci sequence in C Language ?

Before writing a program to display the Fibonacci sequence , it is important to understand what exactly is the Fibonacci sequence.

It is a series where the next number is the sum of the previous 2 numbers in the sequence. By default , the first two numbers are 0 and 1.

#include <stdio.h>
int main()
    printf("Abundantcode.com's coding sample\n");
    int number1 = 0, number2 = 1, nextnumber = 0, input;

    printf("Enter a number: ");
    scanf("%d", &input);
    printf("Fibonacci Series: %d, %d, ", number1, number2);
    nextnumber = number1 + number2;
    while(nextnumber <= input)
            printf("%d, ",nextnumber);
        number1 = number2;
        number2 = nextnumber;
        nextnumber = number1 + number2;
    return 0;
