What is a Ternary Operator in C++?

A ternary operator in C++ is a symbol that executes conditional logic. If the specified condition is true, expression1 is executed; otherwise, expression2 takes effect. Frequently referred to as a conditional operator, it utilizes the ?: notation.

Syntax:

condition ? expr1 : expr2;

Where,

• condition: A Boolean expression.
• expr1: Executes if the condition evaluates to true.
• expr2: Executes if the condition evaluates to false.

Example:

var isMobile = window.innerWidth “);

editor66899.setValue(decodedContent); editor66899.clearSelection();

editor66899.setOptions({ maxLines: Infinity });

function decodeHTML66899(input) { var doc = new DOMParser().parseFromString(input, “text/html”); return doc.documentElement.textContent; }

// Function to copy code to clipboard function copyCodeToClipboard66899() { const code = editor66899.getValue(); // Get code from the editor navigator.clipboard.writeText(code).then(() => { jQuery(“.maineditor66899 .copymessage”).show(); setTimeout(function() { jQuery(“.maineditor66899 .copymessage”).hide(); }, 2000); }).catch(err => { console.error(“Error copying code: “, err); }); }

function runCode66899() { var code = editor66899.getSession().getValue();

jQuery(“#runBtn66899 i.run-code”).show(); jQuery(“.output-tab”).click();

jQuery.ajax({ url: “https://intellipaat.com/blog/wp-admin/admin-ajax.php”, type: “post”, data: { language: “cpp”, code: code, cmd_line_args: “”, variablenames: “”, action:”compilerajax” }, success: function(response) { var myArray = response.split(“~”); var data = myArray[1];

jQuery(“.output66899”).html(“

"+data+"");
            jQuery(".maineditor66899 .code-editor-output").show();
            jQuery("#runBtn66899 i.run-code").hide();
        }
    });
}

function closeoutput66899() {
    jQuery(".maineditor66899 .code-editor-output").hide();
}

// Attach event listeners to the buttons
document.getElementById("copyBtn66899").addEventListener("click", copyCodeToClipboard66899);
document.getElementById("runBtn66899").addEventListener("click", runCode66899);
document.getElementById("closeoutputBtn66899").addEventListener("click", closeoutput66899);


Output:



The code illustrates how the ternary operator determines the greater of two integers a and b, with the resultant value displayed.



Nested Ternary Operators in C++

Nested ternary operators consist of ternary expressions situated within other ternary expressions. They offer a method for assessing multiple conditions easily, although they can compromise clarity.

Syntax:

condition1 ? expr1 : (condition2 ? expr2 : expr3);
Example:
``````html
 Execute Code
									
								

Code Copied!

var isMobile = window.innerWidth “);

editor85163.setValue(decodedContent); // Assign the default text editor85163.clearSelection();

editor85163.setOptions({ maxLines: Infinity });

function decodeHTML85163(input) { var doc = new DOMParser().parseFromString(input, “text/html”); return doc.documentElement.textContent; }

// Function to copy code to clipboard function copyCodeToClipboard85163() { const code = editor85163.getValue(); // Retrieve code from the editor navigator.clipboard.writeText(code).then(() => { // alert(“Code copied to clipboard!”);

jQuery(“.maineditor85163 .copymessage”).show(); setTimeout(function() { jQuery(“.maineditor85163 .copymessage”).hide(); }, 2000); }).catch(err => { console.error(“Error copying code: “, err); }); }

function runCode85163() {

var code = editor85163.getSession().getValue();

jQuery(“#runBtn85163 i.run-code”).show(); jQuery(“.output-tab”).click();

jQuery.ajax({ url: “https://intellipaat.com/blog/wp-admin/admin-ajax.php”, type: “post”,

data: { language: “cpp”, code: code, cmd_line_args: “”, variablenames: “”, action:”compilerajax” }, success: function(response) { var myArray = response.split(“~”); var data = myArray[1];

jQuery(“.output85163”).html(“

"+data+"");
									jQuery(".maineditor85163 .code-editor-output").show();
									jQuery("#runBtn85163 i.run-code").hide();
								}
							})
						}
		function closeoutput85163() {	
		var code = editor85163.getSession().getValue();
		jQuery(".maineditor85163 .code-editor-output").hide();
		}
    // Attach event listeners to the buttons
    document.getElementById("copyBtn85163").addEventListener("click", copyCodeToClipboard85163);
    document.getElementById("runBtn85163").addEventListener("click", runCode85163);
    document.getElementById("closeoutputBtn85163").addEventListener("click", closeoutput85163);
    
Output:

This snippet illustrates how the nested ternary operator is utilized to determine the maximum among three integers, a, b, and c, with the outcome being displayed according to the evaluated conditions in a sequential manner.

Benefits of the Ternary Operator in C++

• Concise syntax: It enables writing conditions and logic in a single line, thereby minimizing the number of lines of code.
• Enhances readability: The ternary operator is straightforward, making the code succinct, and thus enhances its readability.
• Good for value assignments: This operator is effective for assigning values without necessitating if-else statements.
• Facilitates easy returns: It provides different values based on the conditions in one line.
• Reduces code length: Ternary helps in shortening the code by alleviating the need for multiple lines of if-else in basic logic.

Drawbacks of the Ternary Operator in C++

• Nested ternary operators complicate the code, making it less understandable due to multiple chains.
• A ternary operator cannot wholly replace the if-else statement. It can merely substitute simple if-else patterns that return or assign values.
• Finding errors in nested ternary operators can be quite challenging.
• Using a ternary operator repeatedly in a single code can lead to complexity and make future edits difficult.

Comparison Between Ternary Operator and If-Else Statement in C++

Best Practices for Utilizing the Ternary Operator in C++

• You should only employ a ternary operator for straightforward and clear conditions.
• Avoid using nested ternary operators unless absolutely necessary within the code.
• Always exercise caution when using the ternary operator alongside return statements.
• Refrain from using increment and decrement operators within ternary expressions.
• Be wary of overusing the ternary operator in your code.
• Use nested ternary operators judiciously, as they can complicate debugging.

Conclusion

The ternary operator in C++ serves well for simple conditional statements. It also boosts readability and allows for easy nesting. However, if overused, it may introduce errors in the code. Therefore, understanding the ternary operator through examples in C++, alongside its benefits and drawbacks, is essential.
