？？？你指的是哪种循环？

by lyhqwq @ 2021-05-05 19:29:28

他的意思可能是这道题用循环怎么做（他已经过了一道用循环做的题，所以他大概率知道循环咋用）

双重循环直接套

for (int i = 1;i<=10000; i++) {
    for (int j = 1; j <= i; j++) {
        a = a + i;
        b++;
        if (b == k) {
            cout << a << endl;
            break;
        }
    }
}
return 0;

} 定义和头文件不写了，你自己做的时候加上吧

include<iostream>

using namespace std; int main() { int n,i,s=0,a,b; cin>>n; a=1; b=0; for(i=1;i<=n;i++) { s=s+a; b=b+1; if(b == a) { b=0; a=a+1; } } cout<<s; }

一种答案（全AC）

#include<iostream>
using namespace std;
int main()
{
    int n,i,s=0,a,b;
    cin>>n;
    a=1;
    b=0;
    for(i=1;i<=n;i++)
    {
        s=s+a;
        b=b+1;
        if(b == a)
        {
            b=0;
            a=a+1;
        }
    }
    cout<<s;
}
