You should write this by 3 for loops, one for i (row), one for j (draw white-spaces), and one for k (draw stars)

Answer 2

line 13 is not char '* '

Answer 3

Wrong syntax in this.. for(i=0,j=4;i<4,j>0;i++,j--)
Use && not comma...

Should be like
for(i=0,j=4; i<4 && j>0; i++,j--){...

'*' only not '* '
Comment last 4lines of star pattern properly...
