Logical operators: &&, ||, !

Logical operators in C programming are used to perform logical operations on boolean expressions or conditions. They allow you to combine multiple conditions and evaluate the result. Here are the logical operators in C:

1. Logical AND (&&):

The `&&` operator returns `1` (true) if both the left and right operands are true. Otherwise, it returns `0` (false).

   Example:

   int result = (5 > 3) && (4 < 6);  // result is 1 (true)

2. Logical OR ( || ):

   The `||` operator returns `1` (true) if either the left or right operand is true. If both operands are false, it returns `0` (false).

   Example:

   int result = (5 > 3) || (4 > 6); // result is 1 (true)

3. Logical NOT (!):

The `!` operator negates the value of the operand. If the operand is true, it returns `0` (false). If the operand is false, it returns `1` (true).

  Example:  

  int result = !(5 > 3);  // result is 0 (false)

Logical operators are typically used in conditional statements (`if`, `while`, `for`) to evaluate multiple conditions and make decisions based on the logical result. They are useful for combining multiple comparisons and creating complex conditions.

Example:

int num = 5;

if (num > 0 && num < 10) {

    // Execute this block if num is greater than 0 and less than 10

    printf("num is between 0 and 10\n");

}

int flag1 = 1;

int flag2 = 0;

if (flag1 || flag2) {

    // Execute this block if either flag1 or flag2 is true

    printf("At least one flag is true\n");

}
