C Program to Print Fibonacci Series Up To N

✅ C Program to Print Fibonacci Series Up To N

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

📘 Explanation:

This program prints the Fibonacci series up to a given limit using a while loop. In Fibonacci series, each number is the sum of the previous two numbers.

• Initialize first two numbers as a = 0 and b = 1.
• Print a while it is less than or equal to the limit.
• Calculate next term using c = a + b.
• Update values: a = b and b = c.
• Repeat until a <= num.

🧾 Sample Output:

Enter the limit:
20
Fibonacci series upto 20
0 1 1 2 3 5 8 13
