Answer 1

First loop is used to print new line, so as to maintain pattern

Second loop prints corresponding no. of stars to create a triangle

think it as a 4×4 grid
first loop is used for rows
second loop is used for columns

Consider:
(place cout<<"\n" after second loop)
when i=1, i.e. 1st row
j=1, i.e. 1 row & 1 star

when i=2, i.e. 2nd row
j=1,2 i.e. 2 rows & 2 stars

when i=3, i.e. 3rd row
j=1,2,3 i.e. 3 rows & 3 stars

when i=4, i.e. 4th row
j=1,2,3,4 i.e. 4 rows & 4 stars

"j" will print a star in the specified columns in the row defined by "i"

Answer 2

because you are reassigning 1 to "j" in the for loop itself, that's what is making it 1 for each unique value of "i"

for(int j=1 <--this is initializing j with 1

Answer 3

you are not exiting from first loop until i<5
second loop gets executed for every iteration of outer loop

Answer 4

ohhhhhhh!!!!!
thnk u very much !!!

Answer 5

yeah !
but after the 1st loop (outer and inner both completed) the value of j suldn't be 2?
why it is starting again from 1 in the 2nd time

Answer 6

then why not I is starting from 1 again??

Answer 7

I mean 'i' which I assigned =1 in the outer loop
