**Tips**: It is recommended to use our online Fibonacci Series calculator for better understanding.

In the following example, we will find the Fibonacci Series between 0 and 100.

C Compiler

#include <stdio.h>
int main()
{
int limit = 100;
int a = 0;
int b = 1;
int c = 0;
printf("Fibonacci series upto %d: \n", limit);
printf("%d %d", a, b);
while(c <= limit)
{
c = a + b;
a = b;
b = c;
if(c <= limit)
printf(" %d", c);
}
return 0;
}

In the following example, we will display the fibonacci series from 0 to any given limit.

C Compiler

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