Create a variable Let's create a variable and give it a value of 3. int a; a = 3 ; Variable a 's info Name a Value 3 Data Type The data type of a variable tells you what kind of data it will hold. We can see in the code above that variable a is an int. int = holds an integer (aka a whole number) char = holds a single character pointer = holds a memory address Variable a 's info Name a Data Type int Value 3 Memory Address The a variable is stored somewhere in your computer's memory.

Let's create a pointer that will point to where our a variable is located. To create a pointer, we need the data type of the variable we will be
