Two approaches leap to mind. First, don't use scanf. Use fgets() which takes a parameter to specify the buffer size, and which leaves any newline characters intact.

Reading a string from a file. Use fgets to read string from files in C. Something like: #include #define BUZZ_SIZE 1024 int main(int argc, char **argv) { char.

A simple loop over the file that prints the buffer content should naturally copy the file intact. Second, use fread() or the common C idiom with fgetc().

These would process the file in fixed-size chunks or a single character at a time. If you must process the file over white-space delimited strings, then use either fgets or fread to read the file, and something like strtok to split the buffer at whitespace. Don't forget to handle the transition from one buffer to the next, since your target strings are likely to span the buffer boundary. If there is an external requirement to use scanf to do the reading, then limit the length of the string it might read with a precision field in the format specifier. In your case with a 999 byte buffer, then say scanf('%998s', str); which will write at most 998 characters to the buffer leaving room for the nul terminator. If single strings longer than your buffer are allowed, then you would have to process them in two pieces. Zsrilanka Sinhala Language Pack there. If not, you have an opportunity to tell the user about an error politely without creating a buffer overflow security hole.

Regardless, always validate the return values and think about how to handle bad, malicious, or just malformed input.

Doing this yourself is an awful idea. It has already solved the problem better than most programmers could if they were given months on end to work on it. As for your specific needs, parsing into arrays and such, check the, particularly on JsonTextReader. Basically, Json.NET handles JSON arrays natively, and will parse them into strings, ints, or whatever the type happens to be without prompting from you. Pioneer Ld-v8000 Manual. Is a direct link to the basic code usages for both the reader and the writer, so you can have that open in a spare window while you're learning to work with this.

This is for the best: Be lazy this time and use a library so you solve this common problem forever.
