        cout<<"Enter the character to be print\n";
        cin>> ch;
        cout<<"Enter the number of lines to be print\n";
        cin>>line;
        cout<<"Traingle : \n";
        for(i=0; i<line; i++)
        {
                for(j=0; j<k; j++)
                 {
          cout<<ch;
          }
        
                k=k+2;
                cout<<"\n";
        }
