History of sizeof

== Syntax ==

int sizeof( type )

== Arguments ==

:type

::The name of a built-in C language data type

== Return ==

Returns the number of bytes required to store a variable of the given data type.

== Description ==

Gives the number of bytes needed to store a variable of the given data type. This is useful when the size of a data type might vary on different computers (eg a 64-bit int requires more bytes than a 32-bit int).

== Example ==

<code>

printf("Size of an int: %d bytes\nSize of a float: %d bytes\nSize of a char: %d bytes", sizeof(int), sizeof(float), sizeof(char));
