This article mainly explains "how to use the fgetc function in C language". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to use the fgetc function in C language.

1. The character returned by the fgetc function is actually the character pointed to by the position pointer in the file stream.

When the fgetc function reads an error, it returns EOF and sets the file error flag bit.

2. This function returns the read characters in the form of unsigned char cast to int, and returns EOF if it reaches the end of the file or if a reading error occurs.

Example

# include # include main () {int c; FILE * fp = fopen ("D:\\ test.txt", "r"); if (fp = = NULL) {printf ("Open file failed!\ n"); exit (1);} while ((c = fgetc (fp))! = EOF) printf ("% c", c); fclose (fp) } at this point, I believe you have a deeper understanding of "how to use the fgetc function in C language".
