#include<ctime>

using namespace std;


int main()
{
	int rows, columns;
	cout << "Please, enter a number of rows: ";
	cin >> rows;
	cout << "Please, enter a number of columns: ";
	cin >> columns;
	cout << "Make a table with random numbers from 0 to 100:";
	vector<vector<int> >table(rows, vector<int>(columns));
	srand(static_cast<unsigned int>(time(0)));
	for (int i = 0; i < rows; i++)
		for (int j = 0; j < columns; j++)
			table[i][j] = rand()%100;
	cout << "\nResulting table: \n";
	for (int i = 0; i < rows; i++)
	{
		for (int j = 0; j < columns; j++)
		{
			cout << table[i][j]<<" ";
		}
		cout << endl;
	}
