Printing Times Tables

Problem

  • Print the 9 x 9 times table
  • Constraint: you can’t go back up or delete once your program has printed to the console. That means your program must print left to right, top to bottom.
  • Question: will the program print the table row by row? Or column by column?
  • How does your brain tell your hand how to write a times table?

Solution

#include <iostream>
 
using namespace std;
 
const int MAX_TABLE_SIZE = 9;
 
int main()
{
	cout << "Here's your times tables" << endl;
 
	// foreach row
	for (int row = 1; row <= MAX_TABLE_SIZE; row++)
	{
		// foreach column in that row
		for (int col = 1; col <= MAX_TABLE_SIZE; col++)
		{
			cout << (row * col) << "\t";
		}
		cout << endl << endl;
	}
 
	system("pause");
	return 0;
}
