# size of char datatype and char array in C

Given a char variable and a char array, the task is to write a program to find the size of this char variable and char array in C.

Examples:

```Input: ch = 'G', arr[] = {'G', 'F', 'G'}
Output:
Size of char datatype is: 1 byte
Size of char array is: 3 byte

Input: ch = 'G', arr[] = {'G', 'F'}
Output:
Size of char datatype is: 1 byte
Size of char array is: 2 byte
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach:
In the below program, to find the size of the char variable and char array:

• first, the char variable is defined in charType and the char array in arr.
• Then, the size of the char variable is calculated using sizeof() operator.
• Then the size of the char array is find by dividing the size of the complete array by the size of the first variable.

Below is the C program to find the size of the char variable and char array:

 `// C program to find the size of ` `// char data type and char array ` ` `  `#include ` ` `  `int` `main() ` `{ ` ` `  `    ``char` `charType = ``'G'``; ` `    ``char` `arr[] = { ``'G'``, ``'F'``, ``'G'` `}; ` ` `  `    ``// Calculate and Print ` `    ``// the size of charType ` `    ``printf``(``"Size of char datatype is: %ld byte\n"``, ` `           ``sizeof``(charType)); ` ` `  `    ``// Calculate the size of char array ` `    ``size_t` `size = ``sizeof``(arr) / ``sizeof``(arr); ` ` `  `    ``// Print the size of char array ` `    ``printf``(``"Size of char array is: %ld byte"``, ` `           ``size); ` ` `  `    ``return` `0; ` `} `

Output:

```Size of char datatype is: 1 byte
Size of char array is: 3 byte
```
