Try 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 following result:
Line 1 - Condition is true Line 2 - Condition is true Line 4 - Condition is not true Line 5 - Condition is true |
