[SupriyaTh]

Hiiiiii. Want to write program in 'c' using loops, which ll give an o/p:

1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1

Can anybody help me out?

I added [ code ] ... [ /code ] tags around that triangle and see how much different
it looks now. w.r.t. you question: sure we can help; what have you done so far
yourself and what is giving you problems?

kind regards,

We can use binomial and reverse of of nos i guess....bt how to use it exactly in a loop?

You could do that; but here's a small hint: suppose you have the following line:

1 4 6 4 1

- starting at the end at the right, add the number to the left of it:

1 4 6 4 5 (5 = 4 + 1)
1 4 6 10 5 (10= 6 + 4)
1 4 10 10 5 (10 = 4 + 6)
1 5 10 10 5 (5 = 1 + 4)

- append a one (1) at the right end:

1 5 10 10 5 1

- and there you have your new line.

A yes, Pascals Triangle.

The easiest way (for me atleast) is to use a nested for loop. One loop to go down the triangle, another to iterate across. Using a 2d matrix also helps.

The question was so straight that I didn't felt if I can add much concept in it. I future I will put pseudo code instead of real code.

Thx.

Yep, that'd be better; a lot of posters simply copy and paste complete real
code and turn it in as if it were their own achievement. Sometimes teachers
search the internet for those answers and we don't want to be pointed at
for helping people to cheat.
