bool

整數

整數包含char, bool, short, unsinged short, int, unsinged int, long, unsinged long

整數型態	占用Byte數量	數值範圍	格式字串	輸出格式
bool	1	0 1	%d	整數

  bool b3 = '0';
  bool b4 = 0;
  cout << "b3=" << b3 << ",b4=" << b4 << endl;

執行結果
b3=1,b4=0

編譯器會自動把true翻譯成整數1，false翻譯成整數0。

  bool b1 = true, b2 = false;
  cout << "b1=" << b1 << ",b2=" << b2 << endl;

執行結果
b1=1,b2=0

因為bool是整數，所以bool能做整數運算。但bool顯示出來只會是0或1，即便設的值是2，顯示出來的值仍是1。

  bool b5 = 1;
  bool b6 = 2;
  cout << "b5 = " << b5 << ", b6 = " << b6 << endl;
  cout << "b5 + b6 = " << b5 + b6 << endl;

執行結果
b5 = 1, b6 = 1
b5 + b6 = 2
