Adjacency Matrix creation along with degree

This is a simple C source code, written in gcc platform (Ubuntu, Linux). It reads data from given input .txt file & generate .dat file as output, which contains the Adjacency matrix along with degree of vertices from the given .txt file. It is for only Unweighted Graph. Note: Must change the path of the files in code. Hence, Pattern is that the first digit is the number of nodes in the graph. Next
