for hexa to binary look at this page HTOI
or you can convert for hexa to decimal look at this function strtol
and then to binary using normal methods.
to find odd or not you can use
if(x & 1 == 1)
//it's odd
else
// it's even
Frage
I need to calculate if a hexadecimal number is odd or even as a C function. Is there any function to do it directly?
If not, is there a function in C to directly convert from hexadecimal to binary?
