Segmentation Fault

[flyvin]

I have a vector full of vectors, and whenever I try to access them I get a segmentation fault. It compiled fine, but then when I ran it I got a error. So I ran a debuger and it said a had a segmentation fault. here is the code:

vector< vector<string> > questions;
//some other code where I add things to the vector

for (int i=0; i < questions.size(); i+=1){
           for (int k=0; k < questions[i].size(); k+=1){
                        cout << questions[i][k]; 
           }
}

Please help.

Hi,
When I fill your vector with strings and then print out the vector with the code you have there, I do not get a segmentation fault. The problem must be in some other part of the code. Can you please post more of the code?
Thanks.

Here is all the code that uses the vector. What I'm doing is getting questions from a text file. The part that says "<<<~~~BREAK~~~ >>>" is just something to separate the questions.

 string StrTmp;
       int IntTmp;
       
       vector< vector<string> > questions;
};
       
Dimo::Dimo(){
             ifstream questionsF("mem/questions.srj");
             string question;
             if (questionsF.is_open()){
                      while(questionsF.eof()==false){
                                                    getline(questionsF, question);
                                                    vector<string> questionV;
                                                    if (question == "<<<~~~BREAK~~~>>>"){
                                                                 questions.push_back(questionV);
                                                                 questions.clear();
                                                                 continue;
                                                    }
                                                    questionV.push_back(question);
                      }
                      
                      for(int i=0; i < questions.size(); i+=1){
                               for (int k=0; k < questions[i].size(); k+=1){
                                   cout << questions[i][k]; 
                               }
                      }
                          
             }else{
                   cout << "There was a problem loading some memory";
             }
             

             questionsF.close();
                   
         
             
};
