scanf("%20s", myStr); <-- How to limit scanf from scanning more than 20 characters into myStr??? I was taught that is correct, however it doesnt seem to work in my application, is there a different way to limit the # of values scanf will read into a string?... Similarly if the input were "17.5", the "%i" will match the first two characters only (the 17), leaving the .5 as unread input for the next call to scanf. Even if the input is correct, as " 29 ", the newline that ended the input is still left unread.

How To Get Length Of Input In C Scanf
I'm not entirely sure about the way to specify that buffer lenght in scanf() and in which order the parameters go (there is a chance that the parameters &str and str.size() need to be reversed and I may be missing a . in the format string).
- Scanf() needs a pointer to the variable that will store input. In the case of a string, you need a pointer to an array of characters in memory big enough to store whatever string is read in. When you declare something like char var, you make space for 100 chars with name referring to the first char and name referring to the 100th char.

- Reading unlimited input strings in C. Ask Question 4. 2. The idea is to write a function that reads string of unknown size from stdin, keep it in dynamically allocated array of unknown size and return a copy of that array. Is this the right approach? Could I be more clear? Would reading the input char-by-char be better than getting bigger chunks at once? #include
