What is the correct syntax for increasing a variable named 'sheep' by 1 using a shortcut operator?

The syntax for increasing a variable using a shortcut operator is represented by the increment operator, which in this case is written as "sheep += 1". This operator is a shorthand for adding a value to the variable itself.

When you use "sheep += 1", it tells the interpreter to take the current value of the variable 'sheep', add 1 to it, and then store the result back in 'sheep'. It’s a very efficient way to perform this operation, reducing the amount of code you have to write and improving readability.

Other expressions, such as "sheep = sheep + 1" do achieve the same result, but they do not utilize the shortcut operator. The expression "sheep =+ 1" is incorrect because it effectively sets the variable 'sheep' to positive 1 rather than incrementing it, and "sheep = sheep + 2" would increase 'sheep' by 2 instead of 1, which is not what the question is asking. Thus, "sheep += 1" is the precise and correct way to increment 'sheep' by 1 using a shortcut operator.
