The assignment operator is used to assign values to a variable called an ‘operand’ (we introduced you to this operator through examples in the last step).
float mBallX; //declares mBallX to be of type float mBallX = 0; //assigns a value of 0 to mBallX
After the execution of above statement the value of the variable
mBallX will be 0. That is, the assignment operator has assigned a value of 0 to
In order to assign a value of
mBallX, you simply need to change the value that comes after the operator.
mBallX = 100;
When you assign a value it’s important to check that it fits within the range the data type accepts.
For example, the
byte data type can only hold values with a minimum value of -128 and a maximum value of 127, so you are not able assign a value of 345 or -6892 to a variable of this data type.
You can check which data type is most appropriate for a particular use in Step 2.4.
