C 程序：显示斐波那契数列

原文： https://www.programiz.com/c-programming/examples/fibonacci-series

在此示例中，您将学习显示前 n 个数字的斐波那契数列（由用户输入）。

要理解此示例，您应该了解以下 C 编程主题：

• C 编程运算符
• C while和do...while循环
• C for循环
• C break和continue

斐波那契数列是一个序列，其中下一项是前两项的和。 斐波那契数列的前两个项是 0，然后是 1。

The Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21

斐波那契数列（最多 n 个词）

#include <stdio.h>
int main() {
    int i, n, t1 = 0, t2 = 1, nextTerm;
    printf("Enter the number of terms: ");
    scanf("%d", &n);
    printf("Fibonacci Series: ");

    for (i = 1; i <= n; ++i) {
        printf("%d, ", t1);
        nextTerm = t1 + t2;
        t1 = t2;
        t2 = nextTerm;
    }

    return 0;
} 

输出

Enter the number of terms: 10
Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,

直到一定数目的斐波那契数列

#include <stdio.h>
int main() {
    int t1 = 0, t2 = 1, nextTerm = 0, n;
    printf("Enter a positive number: ");
    scanf("%d", &n);

    // displays the first two terms which is always 0 and 1
    printf("Fibonacci Series: %d, %d, ", t1, t2);
    nextTerm = t1 + t2;

    while (nextTerm <= n) {
        printf("%d, ", nextTerm);
        t1 = t2;
        t2 = nextTerm;
        nextTerm = t1 + t2;
    }

    return 0;
} 

输出

Enter a positive integer: 100
Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89,
