What is C++ control statement?

- Sequential: default mode. …
- Selection: used for decisions, branching — choosing between 2 or more alternative paths. …
- Repetisjon: brukes til looping, dvs. gjenta et stykke kode flere ganger på rad.
Is while a control statement?
I de fleste dataprogrammeringsspråk er en while-løkke en kontrollflytsetning som lar kode utføres gjentatte ganger basert på en gitt boolsk tilstand. While-løkken kan betraktes som en repeterende if-setning.
What is the use of goto statement?

Bruk else if for å spesifisere en ny betingelse som skal testes, hvis den første betingelsen er usann.
What is a JavaScript statement?
Statements are used in JavaScript to control its program flow. Unlike properties, methods, and events, which are fundamentally tied to the object that owns them, statements are designed to work independently of any JavaScript object.
What are JavaScript functions?
A function in JavaScript is similar to a procedure—a set of statements that performs a task or calculates a value, but for a procedure to qualify as a function, it should take some input and return an output where there is some obvious relationship between the input and the output.
