Fibonacci Series Generator

Learn how to generate the Fibonacci series in C using this attractive program.

            
#include <stdio.h>

int main() {
    int n, first = 0, second = 1, next;

    printf("Enter the number of terms: ");
    scanf("%d", &n);

    printf("Fibonacci Series: ");

    for (int i = 0; i < n; i++) {
        if (i <= 1) {
            next = i;
        } else {
            next = first + second;
            first = second;
            second = next;
        }
        printf("%d ", next);
    }

    return 0;
}
            
        

Explanation

1. Step 1: The program starts by including the standard input/output library stdio.h.
2. Step 2: In the main() function, integer variables n, first, second, and next are declared.
3. Step 3: The program prompts the user to enter the number of terms in the Fibonacci series.
4. Step 4: The program generates and prints the Fibonacci series using a for loop.
5. Step 5: The next term is calculated by adding the first and second terms. The values of first and second are updated accordingly.
