打印以图案： * * * * * * * * * * * * * * * * * * * * * * * * * （1）用字符数组方法；（2）用string方法。c++

以下是两种C++打印该图案的方法：
引用:

#include <iostream>
using namespace std;

int main() {
    for (int i = 0; i < 5; i++) {
        for (int j = 0; j < i * 2; j++) {
            cout << " ";
        }
        cout << "* * * * *" << endl;
    }
    return 0;
}

引用[2]:

#include <iostream>
#include <string>
using namespace std;

int main() {
    int n = 4;
    int sum;
    char ch = ' ';
    for (int i = 1; i <= n; i++) {
        for (int j = 1; j <= 3 * (n - i); j++) {
            cout << " ";
        }
        cout << '"';
        for (sum = 2 * i - 1; sum >= 2; sum--) {
            cout << ch << ch << ch;
        }
        cout << endl;
    }
    for (int i = n - 1; i >= 1; i--) {
        for (int j = 1; j <= 3 * (n - i); j++) {
            cout << " ";
        }
        cout << '"';
        for (sum = 2 * i - 1; sum >= 2; sum--) {
            cout << ch << ch << ch;
        }
        cout << endl;
    }
    return 0;
}
