Working with Boolean Expressions in C++
Boolean expressions evaluate to true
or false
. They are commonly used in conditional statements like if
, while
, and for
loops.
Example: Using Boolean Expressions
int a = 10;
int b = 20;
bool result = (a < b);
if (result) {
std::cout << "a is less than b" << std::endl;
} else {
std::cout << "a is not less than b" << std::endl;
}
Explanation: The expression (a < b)
evaluates to true
because 10 is less than 20. The variable result
stores this Boolean value, which is then used in the if
statement.
Key Takeaways
- Boolean expressions result from comparison or logical operations.
- They are essential for controlling program flow.
- Understanding Boolean logic is crucial for programming.
