Thread: Typecast from int to hexadecimal...

I know how to type cast from int to char, but how would you do the same thing from int to hex, any ideas, thanks in advance...

>but how would you do the same thing from int to hex

Code:

int dec = 27;
int hex = dec;

Any questions? The only difference between decimal and hexadecimal is how you represent the value. 27 and 1B are the same exact same value, they're just represented in a different way (such as when you print with the hex modifier).

...what they said.


If you want to output an int value in hex format you can do this:

Code:

#include <iostream>
#include <iomanip>
...
int value = 32;
std::cout << std::hex << value << std::endl;

Should output: 20

and if you want to show the base output std::showbase to the stream so it would show 0x20
