Runtime error

Mehedi Hasan asked 10 months ago

//Can anyone tell why i'm getting runtime error?

include include

using namespace std; int main() { int n; float a,b,c; float sum[200]; cin>>n; for(int i=0; i<n; i++) { cin>>a>>b>>c; sum[i] = (((a2.0)+(b3.0)+(c*5.0))/10); } for(int i=0; i<n; i++) { cout<<fixed<<setprecision(1)<<sum[i]<<"\n"; } }

    Meu código, foi aceito:

    include include include include

    using namespace std;

    int N;

    int main(){ cin >> N; double vetor[N],somatorio[N],somatorio1[N],somatorio2[N],total[N]; for(int i=0;i<N;i++){ cin>>vetor[0]>>vetor[1]>>vetor[2]; somatorio[i]=(vetor[0]2)/10; somatorio1[i]=(vetor[1]3)/10; somatorio2[i]=(vetor[2]*5)/10; total[i]=somatorio[i]+somatorio1[i]+somatorio2[i]; } for(int j=0;j<N;j++){ cout<<setprecision(1)<<fixed<<total[j]<<endl; } return 0; }

    You do not have the value of N, it can be 10 or even 1000000. You can read the information and print without the need for a vector, or declare float sum[1000000]. It's possible to use vectors in c++ with no defined size:

    #include <vector>
    int main(){
      vector<float> sum;
      for(int i=0; i<n; i++){
      ///To print use for each
      for(auto g: sum)
        cout << g << endl;
      /// Or normal for
      for(int i=0; i<n; i++)
        cout << sum[i] << endl;
       return 0;
