C program to print the Fibonacci series

#include <stdio.h>

int main(void) {
    int n, a = 0, b = 1, next;

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

    for (int i = 1; i <= n; i++) {
        printf("%d ", a);
        next = a + b;
        a = b;
        b = next;
    }
    printf("\n");
    return 0;
}

Output:

How it works

• We start with a = 0 and b = 1.
• In each round we print a, then move forward: a takes the value of b, and b takes the new sum.
