Variables are containers for storing data values, like numbers and characters. In C, there are different types of variables (defined with different keywords), for example: int - stores integers (whole numbers), without decimals, such as 123 or -123; float - stores floating point numbers, with decimals, such as 19.99 or -19.99

The integer datatype in C is used to store the integer numbers (any number including positive, negative and zero without decimal part). Octal values, hexadecimal values, and decimal values can be stored in int data type in C. 1. Range: -2,147,483,648 to 2,147,483,647 2. Size:4 bytes 3. Format Specifier:%d
Character data type allows its variable to store only a single character. The size of the character is 1 byte. It is the most basic data type in C. It stores a single character and requires a single byte of memory in almost all compilers. 1. Range: (-128 to 127) or (0 to 255) 2. Size:1 byte 3. Format Specifier:%c
In C programming float data typeis used to store floating-point values. Float in C is used to store decimal and exponential values. It is used to store decimal numbers (numbers with floating point values) with single precision. 1. Range: 1.2E-38 to 3.4E+38 2. Size:4 bytes 3. Format Specifier:%f
A Double data typein C is used to store decimal numbers (numbers with floating point values) with double precision. It is used to define numeric values which hold numbers with decimal values in C. The double data type is basically a precision sort of data type that is capable of holding 64 bits of decimal numbers or floating points. Since double ha...
The void data type in C is used to specify that no value is present. It does not provide a result value to its caller. It has no values and no operations. It is used to represent nothing. Void is used in multiple ways as function return type, function arguments as void, and pointers to void.
The size of the data types in C is dependent on the size of the architecture, so we cannot define the universal size of the data types. For that, the C language provides the sizeof() operator to check the size of the data types.
Example - Declaring a variable and assigning a value. You can define a variable as an integer and assign a value to it in a single declaration. For example: int age = 10; In this example, the variable named age would be defined as an integer and assigned the value of 10. Below is an example C program where we declare this variable and assign ...
Oct 11, 2024 · In C programming language, the variables should be declared before a value is assigned to it. For Example: // declaration of variable a and // initializing it with 0. int a = 0; // declaring array arr and initializing // all the values of arr as 0. int arr[5] = {0}; However, variables can be assigned with 0 or 1 without even declaring them. Let us

Feb 1, 2020 · We can use the sizeof() operator to check the size of a variable. See the following C program for the usage of the various data types: # include <stdio.h> int main { int a = 1; char b = 'G'; double c = 3.14; printf ("Hello World!\n"); //printing the variables defined above along with their sizes printf ("Hello! I am a character.

Integers are whole numbers that can have both zero, positive and negative values but no decimal values. For example, 0, -5, 10. We can use int for declaring an integer variable. int id; Here, id is a variable of type integer. You can declare multiple variables at once in C programming. For example, int id, age;
