Star Pattern in c Programming

In this article, I have shared the list of all Star (*) pattern programs in the c programming language. We will learn to create different patterns or a geometrical shape such as square, triangle, etc. To understand these Star Pattern in C programming examples, you should have the knowledge C programming topics such as C for Loop, C if .else Statement, C while and do…while Loop, C break and continue statement.

I have used Code:: Blocks IDE for debugging purposes. But you can use any C programming language compiler as per your availability.
