Conditional operators

• In C, the conditional operator, also known as the ternary operator, is a shorthand way of writing an if-else statement. It has the following syntax:
  condition ? expression1 : expression2;
• If condition is true, expression1 is evaluated and becomes the result of the entire expression.
• If condition is false, expression2 is evaluated and becomes the result.

Syntax to define constant

• const data_type var_name = value;

Examples :

• Defining using #define preprocessor
• We can also define a constant in C using #define preprocessor. The constants defined using #define are macros that behave like a constant. These constants are not handled by the compiler, they are handled by the preprocessor and are replaced by their value before complication.
• Example:
  int x = 10;
  int y = 20;
  int max = (x > y) ? x : y; // If x is greater than y, max will be x, otherwise y
