すべての行をチェックしましたが、削除を忘れた場所が見つかりませんでした。このサイトでコードを見つけAllocateDynamicArray
てFreeDynamicArray
コーディングし、それが正しいと思います。valgrind の出力をできるだけ早く提供します。どんな助けでも大歓迎です。
template <typename T>
T **AllocateDynamicArray(int nRows, int nCols) {
T **dynamicArray;
dynamicArray = new T*[nRows];
for (int i = 0; i < nRows; i++) {
dynamicArray[i] = new T [nCols];
for (int j = 0; j < nCols; j++) {
dynamicArray[i][j] = 0;
}
}
return dynamicArray;
}
template <typename T>
void FreeDynamicArray(T** dArray, int nRows) {
for (int i = 0; i < nRows; i++) {
delete[] dArray[i];
}
delete[] dArray;
}
int main(int argc, char* argv[]) {
int numOfComps = 1;
int** input = AllocateDynamicArray<int>(rowNo, 4);
while (calculateAvgTime(false) > maxAvgTime) {
numOfComps++;
}
FreeDynamicArray(input, rowNo);
return EXIT_SUCCESS;
}
double calculateAvgTime(bool print) {

int* computers = new int[numOfComps];
for (int i = 0; i < numOfComps; i++) {

}

//some code related to computers and infoList
double waitingTime /= (double) (rowNo);
FreeDynamicArray(infoList, numOfComps);

return waitingTime;
}
以下は、valgrind の出力です。
