Question

What are the logical operators in C?

Answer 1

Logical operators are used to perform logical operations on conditions. They return either 0 (false) or 1 (true). Here are the logical operators in C:

• Logical AND (&&): Returns true if both conditions on the left and right are true.

  int x = 5;
  int y = 10;
  int result = (x > 0 && y < 20); // result = 1 (true)
   

• Logical OR (||): Returns true if either of the conditions on the left or right is true.

  int a = 5;
  int b = 10;
  int result = (a > 0 || b > 20); // result = 1 (true)
   

• Logical NOT (!): Returns true if the condition is false and false if the condition is true.

  int flag = 0;
  int result = !flag; // result = 1 (true)
