size of char datatype and char array in C Last Updated : 15 Oct, 2019 Comments Improve Suggest changes Like Article Like Report 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 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 // C program to find the size of // char data type and char array #include <stdio.h> 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[0]); // 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 Comment More infoAdvertise with us Next Article size of char datatype and char array in C C code_r Follow Improve Article Tags : C Programs C Language C-Data Types Similar Reads How to Find the Size of an Array in C?

In C, a structure is a user-defined data type that can be used to group items of different types into a single entity while an array is a collection of similar data elements.

The length of a character array is defined as the total number of characters present in the array, excluding the null character ('\0') at th 2 min read Advantages and Disadvantages of Array in C An array is a data structure that stores a collection of elements, all of the same data type, in a contiguous block of memory. Each element in the array is identified by an index, which is a numerical value that represents the position of the element in the array. The first element in the array has 8 min read Like
