Pascal Triangle is started by 1, then followed by The binomial coefficient (n,k),
where n is the non negative integer and k is the integer between 0 and n.
Pascal triangle is the triangular array.

3 comments on “C Program to print Pascal’s Triangle”
Nice code, however it does not actually print out pascal's triangle. My output was:
1
1
12
123
Whereas the real pascal's triangle is:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
etc.
whoops… sort of.
My output was actually:
1
121
12321
1234321
however this is still not pascals triangle.
Hello,
Thanks for pointing out the error. I agree, it wasn't printing Pascal's triangle at all. Sorry for that.
Check the fixed program and let me know if it works for you.
Feel free to share your feedback.
