reinterpret_cast本质

reinterpret_cast本质

reinterpret_cast 可以将一个类型所包含二进制内容，重新解释为另一种类型。

#include < iostream > 
using   namespace  std;

void  main() 
{ 
     int  i  =   875770417 ; 
    cout << i << " " ;
     char *  p  =  reinterpret_cast < char *> ( & i);
     for ( int  j = 0 ; j < 4 ; j ++ )
        cout << p[j];
    cout << endl;

     float  f  =   0.00000016688933 ;
    cout  << f << " " ;
    p  =  reinterpret_cast < char *> ( & f);
     for (int j = 0 ; j < 4 ; j ++ )
        cout << p[j];
    cout << endl;
}
