Ternary Expression Conditional Statement
The ternary operator is a shorthand way of writing an if-else statement. It takes three operands: a condition, a result for when the condition is true, and a result for when the condition is false.
Syntax of Ternary Expression:
condition ? result_if_true : result_if_false
Use Cases of Ternary Expression:
- Concise conditional assignment.
- Inline conditional assignment.
Applications of Ternary Expression:
- Assigning values based on conditions in functional programming.
- Inline conditional assignment in single lines of code.
Advantages of Ternary Expression:
- Concise syntax, reducing the need for multiple lines of code.
- Suitable for simple conditional assignments.
Disadvantages of Ternary Expression:
- Can reduce code readability, especially for complex conditions or expressions.
- Limited to simple assignments; not suitable for complex branching logic.
Implementation of Ternary Expression:
#include <iostream>;
using namespace std;
int main()
{
int x = 10;
string result
= (x > 0) ? "x is positive" : "x is not positive";
cout << result;
return 0;
}
import java.util.Scanner;
public class Main {
public static void main(String[] args)
{
// Define an integer variable x and assign the value
// 10 to it
int x = 10;
// Use a ternary operator to check if x is positive
// or not If x is greater than 0, assign "x is
// positive" to the result variable Otherwise,
// assign "x is not positive" to the result variable
String result = (x > 0) ? "x is positive"
: "x is not positive";
// Print the result to the console
System.out.println(result);
}
}
# Define an integer variable x and assign the value
# 10 to it
x = 10
# Use a ternary operator to check if x is positive
# or not. If x is greater than 0, assign "x is
# positive" to the result variable. Otherwise,
# assign "x is not positive" to the result variable.
result = "x is positive" if x > 0 else "x is not positive"
# Print the result to the console
print(result)
// Define an integer variable x and assign the value
// 10 to it
let x = 10;
// Use a ternary operator to check if x is positive
// or not. If x is greater than 0, assign "x is
// positive" to the result variable. Otherwise,
// assign "x is not positive" to the result variable.
let result = x > 0 ? "x is positive" : "x is not positive";
// Print the result to the console
console.log(result);
Output
x is positive
Conditional Statements in Programming | Definition, Types, Best Practices
Conditional statements in programming are used to control the flow of a program based on certain conditions. These statements allow the execution of different code blocks depending on whether a specified condition evaluates to true or false, providing a fundamental mechanism for decision-making in algorithms. In this article, we will learn about the basics of Conditional Statements along with their different types.
