21 sie 2012 · To find out the end of the file with symbols you can use EOF. For example: char symbol; FILE *in = fopen("./task.in", "r"); for ( ; fscanf(in, "%c", &symbol) != EOF; ) { printf("%c", symbol); }
If an end-of-file condition is detected before any matches are performed, including matches against whitespace and literal characters in the template, then WEOF is returned. Function: int fscanf (FILE * stream , const char * template , …) ¶
4 lip 2022 · 1) reads the data from stdin. 2) reads the data from file stream stream. 3) reads the data from null-terminated character string buffer. Reaching the end of the string is equivalent to reaching the end-of-file condition for fscanf.
Reaching the end of the string in sscanf () is equivalent to encountering end-of-file for fscanf (). If conversion terminates on a conflicting input, the offending input is left unread in the input. Any trailing white space (including newline characters) is left unread unless matched by a conversion specification.
Reaching the end of the string in sscanf() shall be equivalent to encountering end-of-file for fscanf(). If conversion terminates on a conflicting input, the offending input is left unread in the input.
This function returns the number of arguments that were assigned values or EOF, a constant defined in stdio.h, if the end of the file has been reached.
