C++ 逻辑运算符

尝试下面的示例来了解C++中可用的所有逻辑运算符。

复制并粘贴下面的C++程序到test.cpp文件中，编译并运行该程序。

#include <iostream>using namespace std;main() {   int a = 5;   int b = 20;   int c ;   if(a && b) {      cout << "Line 1 - Condition is true"<< endl ;   }   if(a || b) {      cout << "Line 2 - Condition is true"<< endl ;   }   /* Let's change the values of  a and b */   a = 0;   b = 10;   if(a && b) {      cout << "Line 3 - Condition is true"<< endl ;   } else {      cout << "Line 4 - Condition is not true"<< endl ;   }   if(!(a && b)) {      cout << "Line 5 - Condition is true"<< endl ;   }   return 0;}

当上述代码被编译和执行时，它产生以下结果 –

Line 1 - Condition is trueLine 2 - Condition is trueLine 4 - Condition is not trueLine 5 - Condition is true
