The ASCII code of character 0 is actually 48, and the character 0 in C language.

There is only one Byte, that is, what is stored in memory is

0 100 1000

(where each 0 or 1 stands for one bit)

And the integer 0,

Its representation in memory is all zeros. In C language, an integer accounts for 4 bytes, and the representation of integer 0 in memory is:

00000000

00000000

00000000

00000000

.

As follows:

tea

c

=

'0';

//Character 0

Internationalorganizations (same as international organizations)

a

=

0;

//Integer 0

printf("%c，

%d\n "，

c，

a)；

//0,0

printf("%d\n "，

c)；

//48

Accepting characters in integer form is actually printing the value of c in memory.

printf("%d\n "，

(c+a))；

//48

printf("%c\n "，

(char)(c+a))；

//0

Output result:

0,0

48

48

You can see the difference between the character 0 and the integer 0 from the above.
