C# Comparison Operators

Comparison operators in C# are used to compare two values or variables. These operators return a boolean value (true or false) depending on the result of the comparison. They are commonly used in conditional statements to control the flow of the program.

Key Topics

Equal to (==)

The == operator checks if two values are equal. It returns true if the values are the same and false otherwise.

Example: Equal to

int a = 10;
int b = 10;
Console.WriteLine(a == b);  // True

Output:

True

Not equal to (!=)

The != operator checks if two values are not equal. It returns true if the values are different and false if they are the same.

Example: Not equal to

int a = 10;
int b = 20;
Console.WriteLine(a != b);  // True

Output:

True

Greater than (>)

The > operator checks if the left-hand value is greater than the right-hand value.

Example: Greater than

int x = 15;
int y = 10;
Console.WriteLine(x > y);  // True

Output:

True

Less than (<)

The < operator checks if the left-hand value is less than the right-hand value.

Example: Less than

int a = 5;
int b = 8;
Console.WriteLine(a < b);  // True

Output:

True

Greater than or equal to (>=)

The >= operator checks if the left-hand value is greater than or equal to the right-hand value.

Example: Greater than or equal to

int a = 10;
int b = 10;
Console.WriteLine(a >= b);  // True

Output:

True

Less than or equal to (<=)

The <= operator checks if the left-hand value is less than or equal to the right-hand value.

Example: Less than or equal to

int x = 7;
int y = 10;
Console.WriteLine(x <= y);  // True

Output:

True

Key Takeaways

  • ==: Returns true if the two values are equal.
  • !=: Returns true if the two values are not equal.
  • >: Returns true if the left-hand value is greater than the right-hand value.
  • <: Returns true if the left-hand value is less than the right-hand value.
  • >=: Returns true if the left-hand value is greater than or equal to the right-hand value.
  • <=: Returns true if the left-hand value is less than or equal to the right-hand value.
