Re: 'if' function

Try explaning your problem in more details
if(CHARACTER == '\n')

CHARACTER is a char type which checks for '\n'

the ascii value of '\n' is 10

if it is a match condition is true and code after the if is executed else not

Re: 'if' function

This looks like a matlab branching function. The double equal signs are a comparison of the variable named character and the \n. This will return a logic true or false which the if statement will act on.

Hi,

I already understand, the ASCII code show the 10=A is LF (Line Feed), that mean the Line Feed is next line izit??

Can you tell me the ASCII function from 0-31 and how to use it, haa...ha... the 32 i know.. is space. The other (33-127) i understand...

Thank you..

Re: 'if' function

CHARACTER is a variable of char type. That means, that somwhere in the program code there should be a line like

char CHARACTER;

'\n' is a C standard char type constant, which means "New Line", an integer value is equal to 10, or 0x0A

Similarly the '\r' is a char type constant that means "Carriage Return" with value 13, or 0x0D.

You can find all ASCII codes on: https://www.lookuptables.com/

Re: 'if' function

The most of ASCII control codes are remnants from very old times of
mechanical terminals.
You can find how this constants are used in on-line book:
