Let's start with the basics! A boolean is like a simple yes or no answer. In computers, we use TRUE for yes and FALSE for no. Think of it like a light switch that can only be ON or OFF. This is the foundation we need to understand before we learn about boolean arrays.
Now let's learn about arrays! An array is like a list or a row of boxes. Each box can hold one item, and the boxes are numbered starting from zero. For example, if we have an array of your favorite colors, box zero might contain red, box one contains blue, box two contains green, and box three contains yellow.
Now we can combine both ideas! A Boolean Array is an array where each box holds a boolean value - either true or false. This is perfect for tracking yes or no questions! For example, if you want to know which friends are coming to your birthday party, you can use a boolean array. Alice is true meaning she's coming, Bob is false meaning he's not coming, Carol is true, and Dave is false.
Now let's see how to write this in C++ code! First, you include the input output stream library. Then you create a boolean array by writing 'bool friends[4]' which creates an array that can hold 4 boolean values. Next, you set the values using square brackets and the index number. friends[0] equals true for Alice, friends[1] equals false for Bob, friends[2] equals true for Carol, and friends[3] equals false for Dave. That's it! You now have a boolean array in C++!
