C Reverse Mirror Right Angle Triangle Star Pattern

Why Star Pattern

In most of the MNC interview questions such as in ZOHO interview questions, IVTL Infoview interview questions, Amazon interview questions, GOOGLE interview questions, Infosys interview questions and even in Voonik interview questions, we come across star pattern questions with a probability of 1:5. We provide you a most commonly asked reverse mirror right angle triangle star pattern question for your interview preparation using C programming.

Reverse Mirror Right Angle Triangle Star Pattern

We challenge you, the programmer to do the reverse mirror right angle triangle star pattern using C programming

Reverse Mirror Right Angle Triangle Star Pattern in C

C Programming logic

1. Consider every single space as 0.

*****
0****
00***
000**
0000*

2. From the above star Pattern, we can easily identify, this c program contains 3 for loop.

  • for loop represents every new line.
  • for loop for displaying 0.
  • for loop for displaying *.

Facts about a Pattern

  • C program is not capable of transferring its control from line 2 to line 1.
  • Thus the programmer need to complete the line 1 before executing the line 2.
