I didn’t understand the concept of logical gates. Is it actually easy? Can you explain it to me in the simplest way possible?

Hi Soumyadeep,

Yes, it’s easier than it seems! Let’s take a simple example using the OR operator (||), which is one kind of logical gate.

The OR operator checks two conditions and gives true if at least one of them is true.

Here’s how it works in code:

if ((age >= 18) || (gpa > 3.5)) {
    printf("You meet the criteria.\n");
}

This line means:
“If the person is 18 or older, or their GPA is above 3.5, then print the message.”

Examples:

• If age is 20 and GPA is 3.0 → it prints (because age ≥ 18)

• If age is 16 and GPA is 3.8 → it prints (because GPA > 3.5)

• If age is 16 and GPA is 3.0 → it doesn’t print (because both are false)

So in simple terms:
OR means only one condition needs to be true for the code to run.

Let me know if you want help understanding other gates like AND or NOT — I’m here to help.
