What does each line of code do in a sequential programming language?

• A. Operates simultaneously
• B. Operates one at a time
• C. Operates randomly
• D. Operates in parallel

Answer: (B)

In a sequential programming language, each line of code operates one at a time, following a specific order. This means that the execution of the code progresses in a linear fashion, where the first line is executed before the second line, the second before the third, and so on. This fundamental characteristic of sequential programming ensures that the output or effect of each line can depend on the preceding lines, maintaining an understandable and predictable flow of operations. This structure contrasts with other types of programming execution, such as parallel or concurrent execution, where multiple lines or blocks of code might run simultaneously or in an interleaved fashion. Sequential execution simplifies debugging and reasoning about the code since each step is processed independently and in sequence.
