In this article, I will write a C program to compare two files contents. A logic to compare two files character by character and line by line in C programming is easy. So the main attraction of this article to describe the steps to how to compare two files character by character and line by line in C programming.
Example,

With the all-new Compare Files tool, you can now quickly and accurately detect differences between two versions of a PDF file. Choose Tools Compare Files. Click Select File at left to choose the older file version you want to compare.
- Easily compare documents or multiple versions of a PDF file using a side-by-side comparison view or single page views to quickly spot changes by eye. With the PDF comparison tool, you can apply filters to view what’s changed by content type, images, text, annotations, or formatting.
- To compare to files you can compare the bytes of each one. 1) read the byte array of file 1 2) read the byte array of file 2 3) use a for loop to check each node of the array 4) inside the loop if its different one of them return false 5) if the loops ends is true. Easy, not much code, maybe 20 lines or less.
Logic to compare two files:
1. Open two files using in read-only mode and get file pointer.
2. Read the characters of both files using fgetc one by one until the end of the file.
3. If variable encounter new line then increments line number and reset position to zero.
4. If variables are not equal then set the flag (isContentMatch) and break the loop using the break statement.
2. Read the characters of both files using fgetc one by one until the end of the file.
3. If variable encounter new line then increments line number and reset position to zero.
4. If variables are not equal then set the flag (isContentMatch) and break the loop using the break statement.
If you want this tutorial in video format then here it is which explains the below program to how to compare two files using C.
Let see the C program to compare two files contents
Output1:
Compare Anything 1 2 – Compare Files File
When both files have the same content.
Output2:
How To Compare 2 Text Files
Anytrans for ios 7 0 4. When both files have different content.
Code Analysis:
I have created a structure to store the mismatch position and the line.
Polarr 3 0 download free. In the above C program to compare two files contents, first, we opened to open both files which you want to compare. Here I am opening two files “aticleworld1.txt” and “aticleworld2.txt” and getting their file pointer. Using the if condition I am verifying that the file is opened successfully or not.
For comparing the file content, I have created a function isFileSame(). It takes file pointer of both file and structure pointer to get the mismatch position and line. In this function, I am using the fgetc function to read the file contents.
In this function, I am using the if condition to increment the line counter on changing of the new line.
