WebFeb 20, 2015 · 23. In C++, there are two types of storage: stack -based memory, and heap -based memory. The size of an object in stack-based memory must be static (i.e. not changing), and therefore must be known at compile time. That means you can do this: int array [10]; // fine, size of array known to be 10 at compile time.

WebJul 13, 2009 · size_t is the unsigned integer type of the result of the sizeof operator (ISO C99 Section 7.17.) The sizeof operator yields the size (in bytes) of its operand, which may be an expression or the parenthesized name of a type. The size is determined from the type of the operand. The result is an integer. WebКроме того, foo<2>({4, 5}); также будет работать. Да, некрасиво, но могло быть и хуже. –

WebIt is because the sizeof() operator returns the size of a type in bytes. You learned from the Data Types chapter that an int type is usually 4 bytes, so from the example above, 4 x 5 (4 bytes x 5 elements) = 20 bytes. To find out how many elements an array has, you have to divide the size of the array by the size of the data type it contains: WebSep 25, 2010 · To an int.
