It doesn't.
Try this
#include <stdio.h>
#include <wchar.h>
int main (void) {
printf ("sizeof (char)=%d, sizeof (wchar_t)=%d\n",
(int)sizeof (char), (int)sizeof (wchar_t));
return 0;
}

How many bytes does date DD-MM-YYYY datatype occupy in java?
A java.util.Date object will take about 32 bytes in memory.
Are pointers integers?
A pointer holds a memory address, from 0 to the upper limit of your memory (in 32 bit addressing this is up to 2^32, 64 bit is up to 2^64 bytes). So in math terms, a pointer could be considered a non-negative integer. However this is not the same as the integer type used in C and other languages, which refers to how the data at that memory address (the raw bits) is interpreted by the system. So the expression "int *x;" declares a pointer to an integer, but x is a memory address, not a literal C-style integer. The value pointed to by x, however, will be interpreted as a literal C-style integer. It may be easier to see using a pointer to a char: char character = 'C'; char *pointerToCharacter = character; In this case, character is a standard char variable, and pointerToCharacter is a pointer (which is a memory address) that points to the location in memory of a character.
What is difference between multi character constant and string literals?
In C, you can assign integers multiple characters such that they fit in their size. For e.g.: int - 4 bytes char - 1 byte So an assignment like this is valid: int a = 'ABCD'; The first byte in a will be assigned the value of 'A', the second - 'B' and so on. A string literal is a character array constant. It is enclosed in double quotes and assignment can only be made to a char pointer. There is no limit on the size of the literal and it is terminated with a null character. e.g.: char str[] = "This is a trial";
