format '%d' expects argument of type 'int

I've class with matrix and getter

class A
  int matrix[20][10];
   auto getter(){return matrix;}

What is a type that auto returned? And how to return it without using auto

You don't really want to specify the return type without auto or a type alias. The usual rules for declarators make it quite ugly. But here it is, just follow the spiral rule:

int (*getter())[10] {return matrix;}

[Solved] What Is Type Int*? Compile Error In C, Re: [Solved] What is type int*? compile error in c. Posted 09 July 2013 - 08:13 AM​. int is just an int (okay, that was a meaningless tautology  int is just an int (okay, that was a meaningless tautology - sorry) and int* is a pointer to int. & creates a pointer. So a has type int and &int has type int*. The last two warnings, which are referring to the line with printf, are telling you that printf, when given the %d modifier, wants a plain int, not a pointer.

auto here gets the type that the function should return automatically. In that case that type is:

int (*)[10]

int* i; or int *i; or int * i;, It is a pointer to a block of memory, of which is type int. – Billy ONeal Sep 26 '10 at 18:17. 10. I would argue that *i has a type of int . – Tim Goodman Sep 27 '10 at  In computer science, an integer is a datum of integral data type, a data type that represents some range of mathematical integers.Integral data types may be of different sizes and may or may not be allowed to contain negative values.

Auto means type is going to be decided according to what you returned. So in this case i believe it is and array that holds int arrays. You can just put the type you want to return instead of auto.

Types, This expression is made up of three parts: the numeric literal 1 (which is of type int ), the + operator (which represents addition) and another numeric literal 1 . The int data type is the primary integer data type in SQL Server. The bigint data type is intended for use when integer values might exceed the range that is supported by the int data type. bigint fits between smallmoney and int in the data type precedence chart. Functions return bigint only if the parameter expression is a bigint data type.

How to Work with Variables, Data Types, and Arithmetic Expressions , The int, float, double, char, and _Bool data types; Modifying data types with short, long, and long long; The rules for naming variables; Basic math  An integer is a whole number — that is, a number with no fractional or decimal portion. Java has four integer types, which you can use to store numbers of varying sizes. Type Number of Bytes Range of Values byte 1 –128 to +127 short 2 –32,768 to +32,767 int 4 –2 billion to +2 …

What is the meaning of <class int> in Python when we use type , In your case you are taking the type of an integer which an instance of class int. Play around. Take the type of a floating point value, a string,  The type of an integer literal is determined by its suffix as follows: If the literal has no suffix, its type is the first of the following types in which its value can be represented: int , uint , long , ulong .

C++11, C++11 is a version of the standard for the programming language C++. It was approved by of “ 0 ” is meant as “a constant expression which evaluates to 0 , which is of type int”. In reality, the constant expression can be of any integral type. Integers are your primary data-type for number storage. On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1). On the Arduino Due and SAMD based boards (like MKR1000 and Zero), an int stores a 32-bit (4-byte

  • Why should one care. Use auto and your life is easy :) And also your title says the type ;)
  • your title and your text are two complementary questions... the answer for one is the other
  • OK, How to do convertation to this type? It does not work ((*)[10])matrix

  • @Hujuk - Also, please note I posted a complete function definition. I didn't say you need to convert anything by casting.
  • @StroryTeller Ok, I understand. Thanks
