need white space character
Posted by matheo917 [send private reply] at August 31, 2001, 08:24:15 PM
can anyone tell me what ASCII character number or any other symbol used by c++ stands for white spaces, i need to add a stopper (delimeter) in my function that stops when it reads in a white space, i am concerned with reading in a text file that will read word after a word, and for example will stop
when it encounteres a space for example "programming forum" for example ifstream fin("c:\\text.txt"); string str; getline(fin, str, 'whitespaceneededhere');

The space character (' ') is 32 decimal (20 hex) in ASCII

Correct me if I am wrong, but in C, why not just put ' ', instead of the value, C should convert it to the value for you?

Yes... or if you're really tricky, you can do all sorts of nasty stuff like...
Subtracting the ASCII value of '0' from the character's ASCII value, to find it's real value!

Only if the ascii character is a number though...

Software Engineering? Let's have Engineers versus (Computer) Scientists wars!
In addition, Mr. Matheo, C has a function isspace() (prototyped in ctype.h) that takes a char code as input and returns whether it is whitespace or not.
