newbie questions

[Connor Clark]

1. How do I find the value of a variable in BYTES instead of getting the
normal data it stores. IE

int a = 23;

cout<<bytevalue(a);


would print some string in binary.

2. Is there an easy way to convert between binary, decimal, and hexadecimal?


Thanks, and sorry in advance if I'm posting in the wrong place and/or doing
something else totally wrong, I've never used a newsgroup before.

Here's some examples:

#include <iostream>
#include <bitset>

int main()
{
int a = 23;

std::cout << "dec " << a << " = hex " << std::hex << a
<< " = octal " << std:ct << a << std::endl;

std::cout << "as a 32 bit binary "
<< std::bitset<32>(a) << std::endl;

return 0;
}

The output should be:

dec 23 = hex 17 = octal 27
as a 32 bit binary 00000000000000000000000000010111
