Decision Statements introduction

Decision statements help the program make choices. It's like when you decide whether to wear a jacket based on the weather. 

The program makes decisions using "if" statements and "else" statements.

If Statement:

Think of it like a question. If something is true, do this; otherwise, skip it.

Example: If it's raining, take an umbrella.

if (weather == raining) {

    takeUmbrella();

}

---

Else Statement:

This is like saying, "If the first thing is not true, do this other thing."

Example: If it's not raining, wear sunglasses.

if (weather == raining) {

    takeUmbrella();

} else {

    wearSunglasses();

}

---

Else If Statement:

Sometimes, there are more than two options. "Else if" helps with that.

Example: If it's raining, take an umbrella; if it's sunny, wear sunglasses; if it's cloudy, wear a hat.

if (weather == raining) {

    takeUmbrella();

} else if (weather == sunny) {

    wearSunglasses();

} else {

    wearHat();

}

Switch Statement:

This is like a menu with different options. Based on a value, it decides what to do.

Example: Depending on the day of the week, do different activities.

switch(day) {

    case Monday:

        doWork();

        break;

    case Friday:

        haveFun();

        break;

    default:

        relax();

}

Remember, these decision statements help the program make choices, just like you do in everyday situations. If something is true, it does one thing; if not, it does something else. This makes the program smart and adaptable.
