Code showing error, please find faults and help me in fixing them

#1

Problem: Cycle detection in an undirected graph
https://practice.geeksforgeeks.org/problems/detect-cycle-in-an-undirected-graph/1#

#2

error is because of wrong use of pointers

you can’t do *c (deference of pointer)
unless you provide the address of a variable to c

i have corrected the segmentation fault only
now you code run but output is still incorrect
first check the code at your own

Modified Code

you don’t have to use parent array if you are using parent variable

Modified code
