help with do while loop

[thelaitor1]

i want to display this (1,2,1,3,1,4,1,5,1,6,1,7,1,8,1,9,1,10) using the do while loop but i'm stuck.

  k = 0;
	do
	{

		cout << ","<< k;
		k = k + 1;
	}while ( k < 20);

You mean something like this?

        int k = 0;
	int j = 1;
	do
	{

		cout << j << ","<< k <<endl;
		k++;
	}while ( k < 20 );

By the way this can be done easy using 2D arrays.

[thelaitor1]

no, i want it to be displayed this way
1,2,1,3,1,4,1,5,1,6,1,7,1,8,1,9,1,10

Well then remove the endl :p not that hard to figure out.

here just compile this whole thing:

#include <iostream>
using namespace std;

int main()
{
	int k = 0;
	int j = 1;
	do
	{

		cout << j << ","<< k <<" ";
		k++;
	}while ( k < 11 );

	return 0;
}

when i run that code

#include <iostream>
using namespace std;

int main()
{
	int k = 0;
	int j = 1;
	do
	{

		cout << j << ","<< k <<" ";
		k++;
	}while ( k < 11 );

	return 0;
}

the output is 1,0 1,1 1,2 1,3 1,4 1,5 1,6 1,7 1,8 1,9 1,10

i want the output to be 1,2 1,3 1,4 1,5 1,6 1,7 1,8 1,9 1,10

[long double main]

Then start k off at 2 instead of 0.

[thelaitor1]

k must set = to 0

[long double main]

Why?

The other option is to have

do
{
    cout << j << "," << k+2 << " ";
    k++;
} while (k+2 < 11);

but I don't see any reason why this is better than just setting the initial value of k to be 2.

[thelaitor1]

does anybody know a different method to do it that uses the if command?

[long double main]

Okay, how about this?

do
{
    if (k < 2)
        continue;
    cout << j << "," << k << " ";
    k++;
} while (k < 11);

thank you
