Test: Scratch - Conditionals & Iteration - Class 10 MCQ

The characters are called sprites. With Scratch, you can make your own interactive stories, animations, games, music, and art.

In computing, a command is a directive to a computer program to perform a specific task.

In computer science, a boolean or bool is a data type with two possible values: true or false. It is named after the English mathematician and logician George Boole, whose algebraic and logical systems are used in all modern digital computers. Boolean is pronounced BOOL-ee-an.

The Repeat Until () block is a Control block and a C block. Blocks held inside this block will loop until the specified boolean statement is true, in which case the code beneath the block (if any) will execute. This loop is in similar nature to a while loop in some other programming languages.

An event, then, is like a message from one thread to another. In Scratch, blocks whose labels begin with "broadcast" signal events whereas blocks whose labels begin with "when" handle events, the latter of which, recall, effectively represent threads themselves.

The wait until () block is a control block and a stack block. The block pauses its script until the specified Boolean condition is true.

Placeholder variables are nontranslatable text strings that stand in for a term or phrase that is used multiple times, or represents a term that shouldn't be translated, such as an official product name.

Specifically, conditionals perform different computations or actions depending on whether a programmer.

The loop "counts" the number of times the body will be executed. This loop is a good choice when the number of repetitions is known, or can be supplied by the user.

A conditional sentence is formed by a main clause (the consequence), a conjunction (if), and a conditional clause (the condition).
