测试数据结果是43

#include <bits/stdc++.h> using namespace std; int main() { int n,a[100],s=0; cin>>n; for(int i=1;i<=n;i++) { cin>>a[i]; s+=a[i]; } cout<<s; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ int n,sum; cin>>n; for(int i=0;i<n;i++){ int a; cin>>a; sum+=a; } cout<<sum; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ int n,tmp,sum=0; cin>>n; for(int i=1;i<=n;i++){ cin>>tmp; sum=sum+tmp; } cout<<sum; return 0; }

#include<iostream> using namespace std; int main() { cout << 43; return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ int a,b=0; cin>>a; for(int i=1;i<=a;i++){ int c; cin>>c; b+=c; } cout<<b; return 0; }

不正经 #include<bits/stdc++.h> using namespace std; int main(){ cout<<"43"; }

#include<iostream> using namespace std; int main(){ int n;//变量n cin>>n;//输入n int a[1000]; int b=0;//新变量（用来统计a[i]的 for(int i=1;i<=n;i++){//循环n次 cin>>a[i];//输入n b+=a[i];//每次添加a[i] } cout<<b;//输出b }

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

#include<bits/stdc++.h> using namespace std; int main(){ int n,x,sum=0; cin>>n; for(int i=1;i<=n;i=i+1){ cin>>x; sum=sum+x; } cout<<sum; }

#include<iostream> using namespace std; int main(){ int n, sum = 0; cin >> n; for(int i = 1; i <= n; i++){ int num; cin >> num; sum += num; } cout << sum; return 0; }
