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

A statement is a block of code that doesn't return anything and which is just a standalone unit of execution. For example-

if(a>=0)
printf("Hello Humen,I'm a statement");

An expression, on the other hand, returns or evaluates a new value. For example -

 if(a>=0)
    return a+10;//This is an expression because it evalutes an new value;

or

 a=10+y;//This is also an expression because it returns a new value.
