Ternary operator in C - Mini Project: Build & Apply

Using the Ternary Operator in C

📖 Scenario: You are creating a simple program to check if a number is even or odd. This is a common task in many programs, like deciding if a number should be treated differently based on its type.

🎯 Goal: Build a C program that uses the ternary operator to decide if a number is even or odd and prints the result.

📋 What You'll Learn

Create an integer variable named number with the value 7

Create a character pointer variable named result to hold the text result

Use the ternary operator to assign "Even" or "Odd" to result based on whether number is even or odd

Print the value of result

💡 Why This Matters

🌍 Real World

Checking if a number is even or odd is a basic task useful in many programs, like games, calculators, or data processing.

💼 Career

Understanding the ternary operator helps write concise and readable code, a skill valued in software development jobs.

1

Create the number variable

Create an integer variable called number and set it to 7.

C

# Your code here

Need a hint?

Use int number = 7; to create the variable.

2

Create the result variable

Create a character pointer variable called result to hold the text result.

C

int number = 7;
// Your code here

Need a hint?

Use const char *result; to declare a string pointer.

3

Use the ternary operator to assign result

Use the ternary operator to assign "Even" to result if number % 2 == 0, otherwise assign "Odd".

C

int number = 7;
const char *result;
// Your code here

Need a hint?

Use result = (number % 2 == 0) ? "Even" : "Odd"; to assign the string.

4

Print the result

Write a printf statement to print the value of result.

C

int number = 7;
const char *result;
result = (number % 2 == 0) ? "Even" : "Odd";
// Your code here

Need a hint?

Use printf("%s\n", result); to print the string.
