File Handling with Read Mode in C language 🖥️ | Step-by-Step Guide | Paresh Programming

In this video, we’ll explore key concepts that every C programmer should know, including:

In C, file handling can be done in different modes depending on the operation you want to perform on the file. When you want to open a file in read-only mode, you can use the "r" mode in the fopen() function.

FILE *fopen(const char *filename, const char *mode);

filename: The name of the file you want to open.
mode: The mode in which you want to open the file.

To open a file in read-only mode, use the mode "r" with fopen(). In this mode, the file pointer is positioned at the beginning of the file, and you can only read the contents of the file. If the file doesn't exist, fopen() returns NULL.
