I am currently learning C and in one slide the professor states that Semicolons added to an expression makes it a statement. While on the other hand it mentioned that all assignments are expressions. Even if those assignments take extra lines and has to be seperated by semicolons.
See here:
int a,b,c;
a = b = c = 10;
int a,b,c;
b = 2;
c = 3;
a = b + c;
Would these be considered all expressions? or statements
Tried looking through resources and got conflicting answers
>Solution :
C11 Standard 6.5.1 An expression is a sequence of operators and operands that specifies computation of a value, or that designates an object or a function, or that generates side effects, or that performs a combination thereof. The value computations of the operands of an operator are sequenced before the value computation of the result of the operator.
C11 Standard 6.8.2 A statement specifies an action to be performed. Except as indicated, statements are executed in sequence.
So in a = b = c = 42; we have 3 assignment expressions and 1 statement.
The expressions are a = <something>, b = <something>, and c = 42. (cf C11 6.5.16)
The statement is equivalent to the English sentence "Set a, b, and c to 42."
