ベクターが正しくクリアされない

Question

ベクターベクターをクリアする際に問題があります。

私はタプル関数を使用して複数の変数を返します。

タプル関数を2回連続して呼び出します（毎回異なるファイルを使用します）。

私は、関数からの出力をチェックすると、私はむしろ vector1.size= vector1.sizeとvector2.size = vector2.sizeより

vector1.size = vector1.size と vector2.size = (vector1.size + vector2.size)

相当を取得します。

これは、ファンクションコールの間にベクトルが正しくクリアされておらず、2番目の出力が最初の出力の上に書き込まれていると考えられます。以下は

私のコードです：

（メイン

）と宣言

tuple<vector<float>, vector<vector<float>>, int> ReadFile(string fileToBeRead); 

vector<float> sadInterpolationStorage; 
vector<vector<float>> sadInterpolationVectorStorage; 
vector<float> userInterpolationStorage; 
vector<vector<float>> userInterpolationVectorStorage; 
int sadAnimationLength; 
int inputAnimationLength; 

int main() { 

    tie(sadInterpolationStorage, sadInterpolationVectorStorage, sadAnimationLength) = ReadFile(sadWalkCycleMocapFile); 

    tie(userInterpolationStorage, userInterpolationVectorStorage, inputAnimationLength) = ReadFile(inputMocapFile); 

cout << sadInterpolationVectorStorage[1].size() << endl; 
cout << userInterpolationVectorStorage[1].size() << endl; 


return 0; 
} 

userInterpolationVectorStorage[1].size()は常に (sadInterpolationVectorStorage[1].size()+ sadInterPolationVectorStorage[1].size()の和に等しくなります。 のどこかでベクターが消去されていないようですが、ReadFile()にはすべての変数が作成されます。

ノー成功を収めて、なぜこれが起こっている把握しようと、過去数時間を費やしてきたので、すべての任意の助けをいただければ幸いです。ご質問がある場合は、私に知らせてください。 乾杯！

Answer 1

それを実演しました。

従って私は、彼らがリセットを取得していなかった、関数の外ですべてのボディベクトル（lowerBackXVector lowerBackYVector lowerBackZVector）などを宣言しました。私は関数内でそれらを定義し、今は完全に動作します。みんなありがとう。
