Sum of fibonacci series in c; Through this tutorial, we will learn how to find sum of fibonacci series using for loop, while loop and function in c programs.
Programs to Sum of Fibonacci Series in C
Let’s use the following programs to find sum of fibonacci series using while loop, for loop and function in c:
- C Program to Sum of Fibonacci Series using For Loop
- C Program to Sum of Fibonacci Series using While Loop
- C Program to Sum of Fibonacci Series using Function
C Program to Sum of Fibonacci Series using For Loop
#include <stdio.h>
int main()
{
int Number, Next, Second = 1, sum = 0;
printf("\n Please Enter the Range Number: ");
scanf("%d",&Number);
for(int First = 0; First <= Number;)
{
printf("%d ", First);
sum = sum + First;
Next = First + Second;
First = Second;
Second = Next;
}
printf("\nThe Sum = %d\n", sum);
}
The output of the above c program; is as follows:
Please Enter the Range Number: 10 0 1 1 2 3 5 8 The Sum = 20
C Program to Sum of Fibonacci Series using While Loop
#include<stdio.h>
int main()
{
int Number, First = 0, Second = 1, Next = 0, sum = 0;
printf("Enter Maximum Number for Fibonacci Series = ");
scanf("%d", &Number);
printf("First %d Fibonacci Series Numbers:\n", Number);
while( First <= Number)
{
printf("%d ", First);
sum = sum + First;
Next = First + Second;
First = Second;
Second = Next;
}
printf("\nThe Sum of Fibonacci Series Numbers = %d\n", sum);
}
The output of the above c program; is as follows:
Enter Maximum Number for Fibonacci Series = 5 First 5 Fibonacci Series Numbers: 0 1 1 2 3 5 The Sum of Fibonacci Series Numbers = 12
C Program to Sum of Fibonacci Series using Function
#include<stdio.h>
int fibonacciSeries(int Number)
{
if ( Number == 0 )
return 0;
else if ( Number == 1 )
return 1;
else
return ( fibonacciSeries(Number - 1) + fibonacciSeries(Number - 2) );
}
int main()
{
int Number, i = 0, j, sum = 0;
printf("\nEnter Maximum Number = ");
scanf("%d", &Number);
printf("Fibonacci Series Numbers up to %d:\n", Number);
for ( j = 0 ; j < Number; j++ )
{
printf("%d ", fibonacciSeries(j));
sum = sum + fibonacciSeries(j);
}
printf("\nThe Sum = %d\n", sum);
}
The output of the above c program; is as follows:
Enter Maximum Number = 5 Fibonacci Series Numbers up to 5: 0 1 1 2 3 The Sum = 7
