Write a C Program to Generate the First N Terms of the Sequence

In this article, we will write a C program to generate the first n terms of the Fibonacci sequence.

Initial Fibonacci numbers are 0 and 1. The next number can be generated by adding two numbers. So 0+1=1. Therefore, the next number can be generated by adding two previous ones. The Fibonacci series is 0 1 1 2 3 5 ……

ALGORITHM: 

Step 1: Start 

Step 2: Read n 

Step 3: Initialize f0 ← 0, f1 ← 1, f ← 0 

Step 4:i=0 

Step 5: 

            while(i<=n) do as follows 

            printf("%d\t",f0); 

            f=f0+f1; 

            f0=f1; 

            f1=f; i=i+1; 

             If not goto step 7 

Step 6: Stop 

FLOWCHART: 

PROGRAM: Write a C Program to Generate the First N Terms of the Sequence

include <stdio.h>
#include <conio.h>

void main()
{
	int f0, f1, f, n, i;
	clrscr();
	printf("ENTER THE VALUE FOR n \n");
	scanf("%d", &n);
	f0 = 0;
	f1 = 1;
	printf("FIBONACCI SEQUENCE FOR THE FIRST %d TERMS:\n", n);
	i = 0;
	while (i < n)
	{
		printf("%d\t", f0);
		f = f0 + f1;
		f0 = f1;
		f1 = f;
		i = i + 1;
	}
}

SAMPLE INPUT:

ENTER THE VALUE FOR n
10

OUTPUT:

FIBONACCI SEQUENCE FOR THE FIRST 10 TERMS:
0 1 1 2 3 5 8 13 21 34
