q=0;
cout<<"\t\t\tDisplay pascal Triangle";
cout<<"\n\n\t\t     Created By:- Hitesh Kumar";
cout<<"\n\n\nHow Many Row Do you want to input:";
cin<<r;

cout<<"\nPascal's Triangle:\n";

while(q<r)
{
for(p=40-3*q;p>0;--p)
cout<<" ";
for(x=0;x<=q;++x)
{
if((x==0)||(q==0))
bin=1;
else
bin=(bin*(q-x+1))/x;
cout<<"      ";
cout<<bin;
}

cout<<"\n\n\n";
++q;
}
