Правильно ли очищена динамическая память массива?

#include <iostream>
#include <cstdlib>
int main() {
	int min_ = 0;
	int b = 0;
	size_t arrayRow;
	size_t arrayColumn;
	int** array_;
	std::cout << "rows: ";
	std::cin >> arrayRow;
	std::cout << "columns: ";
	std::cin >> arrayColumn;
	array_ = new int* [arrayRow];
	for (size_t i = 0; i < arrayRow; i++) {
		array_[i] = new int[arrayColumn];
		min_ = 0;
		b = b++;
		for (size_t j = 0; j < arrayColumn; j++) {
			array_[i][j] = 1 + rand() % 100;
			std::cout << array_[i][j] << "  ";
			if (array_[i][j] < array_[i][min_]) {
				min_ = j;
			}
		}
		std::cout << "b[" << b << "] = " << array_[i][min_] << std::endl;
	}
	for (int i = 0; i < arrayRow; i++)
	{
		delete[] array_[i];
	}
	delete[] array_;
	system("pause");
	return 0;
}

Да, похоже на правду.
