Fgetc Read File - 2214445.com

To read the file, we must open it first using any of the mode, for example if you only want to read the file then open it in "r" mode. Based on the mode selected during file opening, we are allowed to perform certain operations on the file. The fgetc function returns the character read. If an error occurs, the fgetc function will set the stream's error indicator and return EOF. If the fgetc function encounters the end of stream, it will set the stream's end-of-file indicator and return EOF. Reads a single-byte unsigned character from the input stream pointed to by stream at the current position, and increases the associated file pointer so that it points to the next character. The fgetc function is not supported for files opened with type=record or type=blocked. In this fgetc in c example, first, we created the File pointer and then assigned the file in read mode because we want to read the characters present in the sample.txt. TIP: Here, we haven’t mentioned the full path of file name because my.c application and the text file reside in the same location.

The characters are then handed over one at a time to the function fgetc, until the buffer is empty.
