Even a simple language such as WHILE can be complex to define. For example, WHILE has three separate syntactic forms—statements, arithmetic expressions, and boolean predicates

5 while Loop Repeatedly execute an instruction or set of instructions as long as (while) a certain condition is met (is true) Repeat A while X is true As soon as X is no longer true, break out of …

Aug 27, 2024 · The body of while loops and for loops contain arbitrary statements, including other loops. Suppose we want to compute and print out a multiplication table like the following:

Putting and between two conditions requires both of them to be true in order for the if statement to execute. Putting or between two conditions allows either of them to be true in order for the if …

Initialize loop vars (vars in loop condition) as necessary. In loop body: update loop vars. Write the rest of the loop body.

This while loop runs as long as the rotation sensor detects less than 360° of spin. As long the condition remains true, motor A and motor B are told to run at full power.

Remember that just as we can use a block of statements in an if statement, we can do the same with a while. In fact, the body of most while loops is more than a single statement.
