Array

[RevvedUp]

Hi, quick question. How do you output its location? Like row 1 column 2. It's a 5 x 5 grid, random numbers from 1 - 10, user asked for what number they're searching for and prints out how many times it appeared. Then print outs the location. Thanks for any inputs

int countNums(int ar[][5], int size, int search) 
{
	int count = 0;
	for (int row = 0; row < 5; row++)
	{
		for (int col = 0; col < 5; col++)
		{
 			if (ar[row][col] == search)
				count++;
		}
	}
	return count;
}

when looking for it..
cout << row << " "<<col;  //+ fancy printing with words and end of lines and things. 

here, 

for (int col = 0; col < 5; col++)
		{
 			if (ar[row][col] == search)
                             {
                                cout << row << " "<<col;
				count++;
                             }
		}

Awesome thanks Jonnin!
