i not clear simple situation

code:

char a='z';

that use assign z a.
question

code:

sizeof(a) gives 1

and z integer value 4 bytes.then how can

code:

char (1 byte)='z'(4 bytes)

statement works.

code:

#include<stdio.h>  int main (){  char c='a'; printf("%d %d", sizeof(c),sizeof('a')); }

the above code give output

code:

1 4

i'm kind of new programming... doesn't character variable act pointer address of data is? perhaps explaination... i'm not sure... in case i'm wrong or plain stupid i'm ready whiplash
