打印 Fibonacci 数列：

#include <stdio.h>

void fibonacci(int n) {

    int i, num1 = 0, num2 = 1, nextNum;

    printf("Fibonacci series up to %d terms:\n", n);

    for (i = 1; i <= n; ++i) {

        printf("%d, ", num1);

        nextNum = num1 + num2;

        num1 = num2;

        num2 = nextNum;

    }

}

int main() {

    int num;

    printf("Enter the number of terms: ");

    scanf("%d", &num);

    fibonacci(num);

    return 0;

}
