例子一：转成二进制
#include<iostream.h>
char a[]="01";
void tentotwo(unsigned int n)
{
if(n)
{
tentotwo(n/2);
cout<<a[n%2];
}
}
void main()
{
unsigned int m;
cin>>m;
tentotwo(m);
}
例子二 转成16进制
#include <iostream.h>
#include <string>
std::string DecToBin(unsigned int value)
{
unsigned int dm = 1 << 15;
char bin[17] = "";
for (int i = 1; i <= 16; i++)
{
bin[i - 1] = ( value & dm ? '1' : '0' );
value <<= 1;
}
return std::string(bin);
}
void main()
{
cout << DecToBin(960).c_str() << endl;
}
