void drawDiamond(int noOfLines,char ch)

{

       if(noOfLines%2!=0)

       {

              for(int i=0;i<noOfLines;i=i+2)

              {

                     for(int j=0;j<(noOfLines-2)-i;j=j+2)

                           cout<<" ";

      

                     for(int k=0;k<i+1;k++)

                           cout<<ch;

              cout<<endl;

              }

              for(int l=0;l<noOfLines-2;l=l+2)

              {

                     for(int m=0;m<l+1;m=m+2)

                           cout<<" ";

    

                     for(int n=0;n<(noOfLines-2)-l;n=n+1)

                           cout<<ch;

        cout<<endl;  

              }

       }

       else

              cout<<"Diamond shape is not possible on even number of lines"<<endl;
