What is sizeof in c programming

Answer 1

Aditya,
Please search the forum first before posting new question. This topic has been discussed before, so it would be nice not to post a duplicate thread 👍

Answer 2

Sizeof() returns the size of a variable. When sizeof() is used with the data types, it simply returns the amount of memory allocated to that data type.

Answer 3

MD. Ferdous Ibne Abu Bakar Sizeof is an operator, not a function. It is not required to use parentheses (except for data types), e.g int a; 'sizeof a' will give 4.

Answer 4

I think this post is a duplicate, btw, sizeof is an operator, not a function.
