I'm studing STL, then i thought "i'll make a 2d array!" but whatever...
a coded this:
vector< vector<int> > vetor;
vetor.resize(10);
vetor[0].resize(10);
for(int i = 0; i < vetor.capacity(); i++){
for(int h = 0; h < vetor[0].capacity();h++){
vetor[i][h] = h;
}
}
Until here, ok. But when i try to show the array value a use this:
for(int i = 0; i < vetor.capacity(); i++){
cout << "LINE " << i << ": ";
for(int h = 0; h < vetor[0].capacity();h++){
cout << vetor[i][h] <<" ";
}
cout << "\n";
}
And the results are really wrong:
LINE 0: 4 5 6 7 8 9 6 7 8 9
LINE 1: 0 1 2 3 0 1 2 3 0 1
LINE 2: 0 1 2 3 0 1 2 3 0 1
LINE 3: 0 1 2 3 0 1 2 3 0 1
LINE 4: 0 1 2 3 0 1 2 3 0 1
LINE 5: 0 1 2 3 0 1 2 3 0 1
LINE 6: 0 1 2 3 0 1 2 3 0 1
LINE 7: 0 1 2 3 0 1 2 3 0 1
LINE 8: 0 1 2 3 0 1 2 3 4 5
LINE 9: 0 1 2 3 4 5 6 7 8 9
What's happening with my program? it isn't printing the right values!
