Answer 1

it's easy !! u need to make 3 loops! first for the no. of rows that's our main loop next a nested loop for spacing!!.. it can be like for(j=1 ;j<=n-i;j++) where i will be the variable in outermost loop (the first one) and n I the no. of rows!! then after this loop the last loop!! for(k=1;k<=i;k++)in this loop u need to print the stars!!
if u still have some questions! u may ask!
