Who created the C programming language?

Dennis Ritchie created the C programming language at Bell Labs in the early 1970s.

intermediate

Why is C called a 'low-level' language?

C is called low-level because it provides direct access to memory and hardware, allowing programmers to write efficient code close to the machine's operations.

What are some common uses of C?

C is commonly used for system software like operating systems, embedded systems, game development, and performance-critical applications.

intermediate

How does C differ from higher-level languages?

C requires manual management of memory and has fewer built-in features compared to higher-level languages, giving programmers more control but requiring more care.

Who developed the C programming language?

A Dennis Ritchie

B Bjarne Stroustrup

C James Gosling

D Guido van Rossum

Dennis Ritchie created C at Bell Labs in the early 1970s.

What type of language is C considered?

A Low-level language

B High-level language only

C Markup language

D Scripting language

C is considered a low-level language because it allows direct memory access and hardware control.

Which of these is a common use of C?

A Database querying
