c++ terinary operator

The ternary operator in C++ allows for a concise way of writing conditional expressions. It takes the form of condition ? trueExpression : falseExpression, where the condition is evaluated and if it is true, the trueExpression is executed and returned as the result of the ternary operator. If the condition is false, the falseExpression is executed and returned as the result.

Here is a step-by-step breakdown of how the ternary operator works:

1. The condition is evaluated to determine its truth value. This can be any expression that evaluates to either true or false.

2. If the condition is true, the trueExpression is executed. This expression can be any valid C++ expression, including function calls, arithmetic operations, or variable assignments.

3. The result of the trueExpression is returned as the result of the ternary operator. This means that if the condition is true, the value of the trueExpression will be the overall result.

4. If the condition is false, the falseExpression is executed. Similar to the trueExpression, the falseExpression can be any valid C++ expression.

5. The result of the falseExpression is returned as the result of the ternary operator. This means that if the condition is false, the value of the falseExpression will be the overall result.

Here is an example to illustrate the use of the ternary operator:

#include <iostream>

int main() {
    int num = 5;
    std::string result = (num > 0) ? "Positive" : "Negative";
    std::cout << result << std::endl;
    return 0;
}

In this example, the condition is (num > 0), which checks if the num variable is greater than 0. If it is true, the trueExpression"Positive" is executed and assigned to the result variable. If the condition is false, the falseExpression"Negative" is executed and assigned to the result variable. Finally, the value of the result variable is printed, which will be "Positive" in this case.
