A pointer however, is a variable that stores the memory address as its value. A pointer variable points to a data type (like int or string) of the same type, and is created with the. operator. The address of the variable you're working with is assigned to the pointer.
- In this C programming tutorial we take a look at variables and data types. If you declare a variable in C (later on we will talk about how to do this), you ask the operating system for a piece of memory. You (can) give this piece of memory a name and you can store something in that piece of memory (for later use).
- Nov 06, 2016 In this video I'll show you how to use different data types other than just integers. I talk about floats, doubles, strings, and chars (aka characters). Subscribe for more tutorials coming soon.
Microsoft Specific
The limits for integer types in C and C++ are listed in the following table. These limits are defined in the C standard header file <limits.h>. The C++ Standard Library header <limits> includes <climits>, which includes <limits.h>.
Microsoft C also permits the declaration of sized integer variables, which are integral types of size 8-, 16-, 32- or 64-bits. For more information on sized integers in C, see Sized Integer Types.

Double Data Type In Dev C Example
If a value exceeds the largest integer representation, the Microsoft compiler generates an error.
