Because a char can be represented by an integer. In fact, if you look at it in
some weird way, a string in C is really just an array of integers terminated
by a 0. So it makes sense to use an int for a single character. Also, the ''
notation can be used.
Example:
#include <stdio.h>
int main(void)
{
int a = 'a';
char b = 'b';
printf("%c = %d = 0x%0.2x\n", a, a, a);
printf("%c = %d = 0x%0.2x\n", b, b, b);
return;
}
%./t
a = 97 = 0x61
b = 98 = 0x62
See?
Cheers,
Emiel
