2-d array function calling

[smc935]

void function1(char array[][80], int r, int c)
{
	for (int i=0; i<r ; i++)
			{
				for (int j=0; j<c ; j++)
				{
					cout << array[i][j];
				}
				cout << endl;
			}
}
void function2(char array[][80], int r, int c)
{
	for (int i=0; i <= r-1 ; r--)
			{
				for (int j=0; j<= c-1 ; j++)
				{
					cout << array[r-1][j];
				}
				cout << endl;
			}
}
void function3(char array[][80], int r, int c)
{
	for (int i=0; i<r ; i++)
			{
				for (int j=0; j<=c-1 ; c--)
				{
					cout << array[i][c-1];
				}
				cout << endl;
			}
}

output:

abcdefghij
bcdefghijk
cdefghijkl
defghijklm
efghijklmn

efghijklmn
defghijklm
cdefghijkl
bcdefghijk
abcdefghij

------------------------------problem here is that it doesnt print out the next array row on function 3.





what am i doing wrong? these are the callers of the function:
function1(array, 5,10);
function2(array, 5,10);
function3(array, 5,10);
< all the same.
