In this program, we are going to share a C program to create a mirror copy of a tree and display using BFS Traversal. If you are a beginner and want to start learning the C programming, then keep your close attention in this tutorial as I am going to share a C program to create a mirror copy of a tree and display using BFS Traversal.
We have designed this program for beginners for learning purpose. Copy below c program and execute it with c compiler to see the output of the program.
