The call that's equivalent to `fgetc` is `fscanf(stream, "%c", &myChar)`. > I… fscanf vs fgetc 11 Years Ago by COKEDUDE What is the difference between fscanf and fgetc? I have a few people arguing with me on the differences. I thought fgetc reads character by character of a file. I thought fscanf reads the whole file. Is that corrrect? Can someone elaborate on what I forgot? Re: fscanf vs fgetc 11 Years Ago by deceptikon > Is that corrrect? Not at all. Have you checked a C reference manual? The only similarities `fgetc` and `fscanf` have is they read input from a stream, and fscanf can simulate `fgetc`. The people you were arguing with, what were their points? Perhaps we can clear up any errors on both sides if you elaborate.

They think fscanf can also read character by character of a file. I do not think that is correct. I think fscanf is used for reading an entire file. I may not be explaing that with the correct terminology but I have used it for reading an entire file before. Re: fscanf vs fgetc 11 Years Ago by gerard4143 One small subtle point. fgetc() reads the next character from stream and returns it as an **unsigned char cast to an int**, or EOF on end of file or error. Re: fscanf vs fgetc 11 Years Ago by COKEDUDE And if you need a char you always cast it like this :). while ((c = fgetc(pFile)) != EOF) { vertices[addcounter] = (char)c; } C fputc and fgetc vs C++ read and write 19 Years Ago by Micko …;); fp2 = fopen ("name", "wb"); while ( (buff = fgetc(fp1)) != EOF) { fputc(buff, fp2); } } [/code] I'm wondering how… Re: C fputc and fgetc vs C++ read and write 19 Years Ago by Micko … text and binary mode.

("r", "w")? Re: fgetc help 18 Years Ago by Ancient Dragon No -- that information is not saved in the FILE structure. Re: Reading Files with fgetc? 17 Years Ago by John A Probably because you're outputting the 'char' as a 'char array'.

Re: fscanf vs fgetc 11 Years Ago by COKEDUDE Thank you :). Were both saying the same thing but can't explain it in a way the other understands. Re: How to concatenate the characters read from a file with fgetc? 8 Years Ago by deceptikon > to determine if it is a number, keyword or an identifier This is a key statement to me, because it sounds like you're writing a lexer. If that's the case, it's not really as simple as throwing characters into an array (or some variation of \*scanf); you need to include some introspective analysis on the characters to properly tokenize … Re: How to concatenate the characters read from a file with fgetc? 8 Years Ago by Jose_12 yes , that is a lexer in "C" ,I have for example the next code in C #include <stdio.h> int main() { printf("Hola mundo"); return 0; } I need to identify the number, words and keywords and the output of the file will be… Re: How to concatenate the characters read from a file with fgetc? 8 Years Ago by AssertNull You could keep track of the LAST character type you extractedand compare it to the current type (i.e. digit). So when you grab a '1', you don't immediately assume you are done extracting the number. You grab the next digit '2' and notice that it's a digit, so you keep going and grab the next character and it's a '3', so you keep going and grab … Re: How to concatenate the characters read from a file with fgetc? 8 Years Ago by Jose_12 I found another way for do my proyect I need to read a txt and store it in a dynamic string array the code I have now does but memory is wasted because it is static I like to read a txt and every word stored in a string array of dynamic #include <stdio.h> #include <conio.h> #define MAX_CHARS 20 … Re: C fputc and fgetc vs C++ read and write 19 Years Ago by Ancient Dragon only write out the number of bytes read. At some point (at end-of-file) the number of bytes read will be less than the buffer size. This would go much faster if you read/write with larger buffer size -- say 255 characters.
