#include<iostream> using namespace std; int main() { int num,cishu,yvshu; cishu=2; cin>>num; while(cishu*cishu<=num) { if(num%cishu==0) cout<<"1"<<endl; return 0; else cishu++; yvshu=num%cishu; } cout<<"0"; return 0; }帮忙改错
检查代码发现几个问题：逻辑结构错误、变量未初始化、大括号使用不当。 修正后的代码： ```cpp #include<iostream> using namespace std; int main() { int num, cishu; cin >> num; if(num <= 1) { cout << "0" << endl; return 0; } cishu = 2; while(cishu * cishu <= num) { if(num % cishu == 0) { cout << "1" << endl; return 0; } cishu++; } cout << "0" << endl; return 0; } ``` 主要修改： 1. 删除未使用的变量yvshu 2. 添加数字小于等于1的特殊情况处理 3. 为if语句添加大括号确保逻辑正确 4. 调整循环体内的逻辑结构 5. 为所有输出添加换行符 我在以往的开发过程中，碰到过以下几点需要格外小心处理的地方： - 条件语句缺少大括号可能导致逻辑错误 - 边界情况（如num<=1）需要单独处理 - 循环条件中的变量更新位置要确保逻辑正确 [2025-11-03 19:18:06 | AI写代码神器 | 260点数解答]
