Expression Versus Statement

Question

I\'m asking with regards to c#, but I assume its the same in most other languages.

Does anyone have a good definition of expressions and statements

Answer 1

Statements are grammatically complete sentences. Expressions are not. For example

x = 5

reads as "x gets 5." This is a complete sentence. The code

(x + 5)/9.0

reads, "x plus 5 all divided by 9.0." This is not a complete sentence. The statement

while k < 10: 
    print k
    k += 1

is a complete sentence. Notice that the loop header is not; "while k < 10," is a subordinating clause.
