英文:
What am I doing wrong in my code that is causing a stack overflow error compared to this similar code?
问题
可以有人请解释一下为什么我的代码会导致堆栈溢出错误，而相似的代码却不会吗？
我的代码
#include<iostream>int main(){using namespace std;int n, k;int score[n]; // 这里可能导致问题int pass=0;cin >> n >> k;for(int i=0; i<n; i++){cin >> score[i];}for(int i =0; i<n; i++){if(score[i]>=score[k-1] && score[i]>0){pass++;}}cout << pass;return 0;}
相似的代码
#include<bits/stdc++.h>using namespace std;int main(){int n,k;int count=0;cin>>n>>k;int a[n];for(int i=0;i<n;i++){cin>>a[i];}for(int i=0;i<n;i++){if(a[i]>=a[k-1] && a[i]>0){count++;}}cout<<count;}
我尝试过更改索引范围和变量名称。

Can someone please explain why my code is causing a stack overflow error while a similar code is not?

I tried changing the index range and also the variable names.

得分: 1
在第一个示例中，score 数组被初始化为长度为 n，但 n 从未被赋值，很可能是零。
在第二个示例中，在给 n 赋值之后才等待初始化 a 数组。这是您想要做的。
英文:
In the first example, the score array is initialized with a length of n, but n was never assigned a value and likely is zero.
In the second example, you wait to initialize the a array until after n was given a value. This is what you want to do.
