Write a C Program to generate the Fibonacci Series starting from any two numbers. The Fibonacci series is a series of numbers in which each number of the Fibonacci series is derived by the adding of its two immediate preceding numbers.

Code:

#include<stdio.h>
 
int main() {
   int first, second, sum, num, counter = 0;
 
   printf("How many Fibonacci terms to display: ");
   scanf("%d", &num);
 
   printf("\nEnter First Number : ");
   scanf("%d", &first);
 
   printf("\nEnter Second Number : ");
   scanf("%d", &second);
 
   printf("\nFibonacci Series: %d  %d  ", first, second);
 
   while (counter < num) {
      sum = first + second;
      printf("%d  ", sum);
      first = second;
      second = sum;
      counter++;
   }
 
   return (0);
}
