Thread: size of char

It's always 1.

It could be, but sizeof will always give you 1. You are interested in CHAR_BIT.

If you make an array of them, yeah. Try compiling and running this program.

Code:

#include <stdio.h>

int main(void) {
    int x;
    printf("Size of char: %d\n", sizeof(char));
    for (x = 2; x < 10; x++)
        printf("Size of %d chars: %d\n", x, (sizeof(char) * x));
    return 0;
}

That should explain it best. The sizeof() operator returns the size of a variable or variable type in size_t. Take a look at these articles, if you're confused:

sizeof - Wikipedia, the free encyclopedia
For, While and Do While Loops in C - Cprogramming.com
Cprogramming.com FAQ > Format output using printf() (C)

He's not talking about making an array. He's talking about the number of bits in a single char. I don't know why you included those other two links, because no one mentioned anything about either of those topics.
