C Program to Merge Two Files2 min read

In this tutorial, we will write a C Program to merge the contents of two files into a third file. Before that, you may go through the following C topics.

Explanation: The program will ask for the two names of the file from where the content is copied and then ask for the third file name where both the files are concatenated and copied there. If the third file is not present then the program will automatically create a file with the entered name.

Lastly, check the third file which will be present in the same directory as the source code.
