Pascal Triangle Program in C with explanation

pascal triangle pattern program in c

In this tutorial we are going to learn writing program in C to print pascal triangle.

But before directly moving on writing program first lets know

What is Pascal Triangle?

Pascal Triangle starts with row n = 0 where there is only one entry 1.

And it grows row wise toward right by adding previous and next item of the previous row.

For example:

  • The initial number in the first row is 1 (the sum of 0 and 1),
  • In second row, addition of 0+1 = 1 and 1+0 = 1. So 1    1 in second row.
  • When we move on 3rd row then 0+1 = 1, 1+1=2 and 1+0 = 1. So elements of triangle in 3rd row is 1   2    1.

Following this approach pascal triangle grows.
