Display a number in hex in C++

[werder85]

Let say I have:

char car=0xE2;

char str[10];

How do I put this value in string?

If I try:

sprintf(str,"%#x",car);

the result will be: 0xffffffe2

But I want to display only 0xe2.

How should I do it?

Thanks a lot

Hi,

Try :

sprintf(str,"%#x",(unsigned char)car);

B.W.

being pointy-haired as i am, i would say that using sprintf() is not C++ !

As LabWindows/CVI is an environment based on ANSI C, the aforementioned approach might actually be best and a consideration for C++ could be considered out of context.

a consideration for C++ is indeed out of context... i was just pointing out the obvious error in the title of the thread.
