What are Source-Level Statements?

What are "source-level statements"?

"Algorithm determines both the number of source-level statements and the number of I/O operations executed" from Computer 开发者_C百科Organization and Design

Statement: A line of code which does something. Source-level means in source code, I guess.

Whatever is called a "statement" by your high-level programming language. Often a source-level statement translates (during compilation) to dozens of machine instructions.

For example, a statement may include a function call, which translates to not only a call instruction, but computation of the arguments, stack-manipulation instructions to push and pop the arguments before and after the call (depending on calling convention). But it would only count as one "source-level" statement.
