Displaying and comparing hexadecimal

[steve1_rm]

Hello,

I would like to display a hex number and compare with another hex number.

I get a hex number from the server. And I want to display this and compare with another hex number.

However, I know you have to use the format specifier x or X. And I guess as I am using a 32 bit cpu. I have been doing this.

printf("%.32x", hexNumber);

The number I am looking for is this. However there could be other ones. But I just want to compare with this. 00000000000000000000000000000401

However, shouldn't there be an 'x' displayed like this. 0x00000000000000000000000000000401

Just one more question how can I compare hex numbers?

if(hexNumber == 0x0000000000000401)
					{
/* numbers are the same do something */
					}

Many thanks for suggestions,

int a = 10;

if ( a == 10 )

if ( a == 0xa )

if ( a == 012 )

There's no such thing as a "hex number".
Base is a representation, it doesn't change the meaning.

The fact that you didn't print an 0x doesn't make it any less comparable to 0x401 or indeed 0x0000401
