New to c++

Hey , it's been a few weeks since I've been learning c++
I got a question ,
I wanted the output to be"
********
*******8
******78
.
.
.
and so on until the last one is going to be
12345678
Instead I get:
********
1*******
12******
.
.
.
.
12345678
so it's the opposite ,
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
#include <iomanip>
#include <iostream>
using namespace std;
int main (){
int c=1,row=1;
while (c<=8){
row=1;
while (row<=8){
if (row<c or c==8)
cout<<row;
else
cout<<"*" ;
row++;
}
cout<<endl;
c++;
}
getchar();
getchar();
return (0);
}

there is error in this code because i hava no compiler but use this approach.
int l=9;
for(int i=0;i<8;i++)
{
for(int m=0;m<8;m++)
{
for(int j=8;j>i;j--)
{
cout<<"*";
}
for(int k=0;k<i;k++)
{
l--;
cout<<l;
}
}
}

@mk12345 Please use code tags
http://www.cplusplus.com/articles/z13hAqkS/
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
#include <iostream>
#include <string>
using namespace std;
int main()
{
string starString = "*********" ;
string numString = "" ;
string tempString = "" ;
for (int i = 0; i < 9; i++)
{
cout << starString << numString;
starString = starString.substr(1);
tempString = numString;
numString = ('8' - i);
numString += tempString;
cout << endl;
}
cin.ignore();
return 0;
}
Here is a recursive approach
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
void star(string myString);
void num(int myNum);
const int MAX_SIZE = 9;
int main()
{
string starString = "*********" ;
star(starString);
cin.ignore();
return 0;
}
void star(string myString)
{
if (myString.size() != 0)
{
cout << myString;
num(myString.size());
cout << endl;
star(myString.substr(1));
cout << endl;
}
}
void num(int myNum)
{
if (myNum != MAX_SIZE)
{
cout << myNum;
num(++myNum);
}
}
