生成金字塔斐波那契数列c++

以下是生成金字塔和斐波那契数列的C++代码示例：

生成金字塔：

#include <iostream>
using namespace std;

int main() {
    int count = 0;
    cout << "请输入要打印多少层：";
    cin >> count;
    
    for (int i = 1; i < count; i++) {
        // 打印空格
        for (int j = 0; j < count - i; j++) {
            cout << " ";        }
        
        // 打印*
        for (int k = 0; k <= i * 2 - 1; k++) {
            cout << "*";
        }
        
        cout << endl;
    }
    
    return 0;
}

生成斐波那契数列：

#include <iostream>
using namespace std;

int fibonacci(int n) {
    if (n <= 1) {
        return n;
    }
    
    int a = 0, b = 1, c;
    for (int i = 2; i <= n; i++) {
        c = a + b;
        a = b;
        b = c;
    }
    
    return b;
}

int main() {
    int n;
    cout << "请输入要计算第几个斐波那契数：";
    cin >> n;
    
    int result = fibonacci(n);
    cout << "第" << n << "个斐波那契数是：" << result << endl;
    
    return 0;
}
