Name the variable types of c, Computer Engineering

Assignment Help:

C provides a wide range of variable types.

All of the integer types plus the char are called the integral types. float and double are called the real types.

Declarations can be spread out, allowing space for an explanatory comment. Variables can also be initialised when they are declared, this is done by adding an equals sign and the required value after the declaration.

int high = 250;    /* Maximum Temperature */

int low = -40;     /* Minimum Temperature */

int results[20];   /* Series of temperature readings */

Type

Explanation

int

char

A single byte of memory, enough to hold a character

short

An integer, possibly of reduced range

long
