使用C/C++，賦值運算時發生的轉換

！

，不管符號位還是數字位；

#include<iostream>
  int_i = ;     
   char_i = int_i;      
   float_i = char_i;   
   bool_i = float_i;    
  cout << showpoint << int_i << << char_i << << float_i << << bool_i <<
   

給短數！這種情況。

#include<iostream><bitset><iomanip>
  int_i =  char_a =<< int_i <<<< char_a <<
<()*> bin_i(int_i);  
  bitset<()*> bin_a(char_a);
  cout << setw() << bin_i <<<< setw() << bin_a <<
  
   

#include<iostream><bitset><iomanip>
  short_i =  long_i =<< short_i <<<< long_i <<
<()*> bin_short_i(short_i); 
  bitset<()*> bin_long_i(long_i);    
  cout << setw() << bin_short_i <<<< setw() << bin_long_i <<
  
   short_j = - long_j =<< short_j <<<< long_j <<
<()*> bin_short_j(short_j); 
  bitset<()*> bin_long_j(long_j);    
  cout << setw() << bin_short_j <<<< setw() << bin_long_j <<
  
   

：

• ；當然這是為了保證long型的值與short型的值相同，因為負數存的是補碼，求值方法是反碼+1；

#include<iostream><bitset><iomanip>
  unsigned_int_i =  signed_int_j =<< unsigned_int_i <<<< signed_int_j <<
<(unsigned )*> bin_i(unsigned_int_i);  
  bitset<(signed )*> bin_j(signed_int_j);
  cout << setw() << bin_i <<<< setw() << bin_j <<
