else if(c=='é')

 

 

else if(c=="é") or else if(c==(unsigned char)'é')

Should work.

When you used 'é', you were specifying it as an integer datatype, where

as "é" is a string/char datatype.

Hi

Thank you?

but

Why is it? the "e" is a string isn't it ? (0xe8 +NULL)

'e' must be unsigned char but It is signed char.

 

Regards

 

According to my ANSI C99 Reference using 'x' denotes it as an integer

where "x" is a char and "xyz" is a char array with an automatic addition

of \n to terminate the sequence.
