C++ 位运算符
尝试以下示例以了解C++中的所有位运算符。
复制并粘贴以下C++程序到test.cpp文件中,并编译并运行此程序。
#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;
}
当上述代码被编译和执行时,它产生以下结果−
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
