C++ 位运算符

尝试以下示例以了解 C++ 中可用的所有位运算符。

复制并粘贴以下 C++ 程序到 test.cpp 文件中，并编译和运行此程序。

#include <iostream>
using namespace std;

main() {
   unsigned int a = 60;	  // 60 = 0011 1100  
   unsigned int b = 13;	  // 13 = 0000 1101
   int c = 0;           

   c = a & b;             // 12 = 0000 1100
   cout << "Line 1 - Value of c is : " << c << endl ;

   c = a | b;             // 61 = 0011 1101
   cout << "Line 2 - Value of c is: " << c << endl ;

   c = a ^ b;             // 49 = 0011 0001
   cout << "Line 3 - Value of c is: " << c << endl ;

   c = ~a;                // -61 = 1100 0011
   cout << "Line 4 - Value of c is: " << c << endl ;

   c = a << 2;            // 240 = 1111 0000
   cout << "Line 5 - Value of c is: " << c << endl ;

   c = a >> 2;            // 15 = 0000 1111
   cout << "Line 6 - Value of c is: " << c << endl ;

   return 0;
}

编译并执行上述代码时，将产生以下结果：

Line 1 - Value of c is : 12
Line 2 - Value of c is: 61
Line 3 - Value of c is: 49
Line 4 - Value of c is: -61
Line 5 - Value of c is: 240
Line 6 - Value of c is: 15
