蓝桥杯基础练习VIP-FJ的字符串

解题思路:

注意事项:

参考代码:

#include <iostream>

#include <string>

using namespace std;

int main()

{

int n;

cin >> n;

char c = 65;

string line = "";

string a = "";

while (n != 0)

{

line += c;

line += a;

a.clear();//清空字符串

a = line;

n--;

c++;

}

cout << line;

return 0;

}
