C++ Logical Operators

Try the following example to understand all the logical operators available in C++.

Copy and paste the following C++ program in test.cpp file and compile and run this program.

#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;
}

When the above code is compiled and executed, it produces the following result:

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