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 byteSize of char array is: 3 byteInput: ch = 'G', arr[] = {'G', 'F'}Output: Size of char datatype is: 1 byteSize of char array is: 2 byteApproach:
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 <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 byteSize of char array is: 3 byte
