int main() {
int n;
cin>>n;

int i,j;

for(i=1;i<=n;i++)
{

for(j=1;j<=(2*n-1);j++)
{

if(j<=i)
cout<<j+" ";

else if((i+j)>=2*n)
cout<<(2*n-j)+" ";


else

The first thing I see wrong is that you have no <filename> after your #include directive.

Please edit your post to use code formatting:

[code] { your source code here } [/code]
