datatypes in C

Yes not python(we already know about that) lets study C : a mini intro

Data-types in C :

Data Type             Memory (bytes)          Range                      Format Specifier

short int                   2          -32,768 to 32,767                       %hd

unsigned short int          2           0 to 65,535                            %hu

unsigned int                4           0 to 4,294,967,295                     %u

int                         4          -2,147,483,648 to 2,147,483,647         %d

long int                    4          -2,147,483,648 to 2,147,483,647         %ld

unsigned long int           4           0 to 4,294,967,295                     %lu

long long int               8          -(2^63) to (2^63)-1                     %lld

unsigned long long int      8           0 to 18,446,744,073,709,551,615        %llu

signed char                 1          -128 to 127                             %c 

unsigned char               1           0 to 255                               %c

float                       4                                                  %f

double                      8                                                  %lf

long double                 12                                                 %Lf

So i was initially having this doubt what is the difference between char and string ? reff: www.sanfoundary.com

A character is just a single character enclosed in single quotes for example :
char initial = 'a';

And a character string is a sequence of 0 or more characters enclosed in double quotes. Each string is terminated by a NULL byte. Therefore string containing 0 character is called an empty string.
example :
char str[] ="How you doin";
char msg[11] = "hello dear";
// for a string containing max 10 characters we have to declare a character array of size 11 bytes.
//i.e. for the last NULL byte for termination
