+# euler-checking-algorithm
+C algorithm that checks if a given graph is Eulerian or not
+
+### Euler Checking Algorithm
+
+This C algorithm takes the text file `euler-graphs.txt` and runs through the input to determine if its contents contain a Euler graph.
+The algorithm checks the initial line of a graph to determine the length of the graph and uses that information to know how many
+lines it must go through to gather all the info of the graph.
+It will repeat this process until it reaches EOF.
+
+Here's an example of graph output (taken from `euler-graphs.txt`):
+
+```
+7
+0 1 1 1 1 1 1
+1 0 1 1 1 1 1
+1 1 0 1 1 1 1
+1 1 1 0 1 1 1
+1 1 1 1 0 1 1
+1 1 1 1 1 0 1
+1 1 1 1 1 1 0
+```
+
+### Setup
+
+Run `make` to generate an executable
+
+which can be executed by running `./EulerCycle`
+
+### Euler Checks
+
+The textfile `euler-graphs.txt` can be modified to check different graphs or the code itself can be modified to use a different text file.
