how many bits long long int take

The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with. This allows great flexibility: for example, all types can be 64-bit.

what is a long long int in c

#include <stdio.h>
#include <stdbool.h>
#include <stdlib.h>

#define FailedToEducate    101
#define Success            400

int main(void) {
	/* 
    	A long int is:
        	32-bit compiler: 
            	MIN: -2,147,483,648
            	MAX: 2,147,483,647
                unsigned MAX: 4,294,967,295
            64-bit compiler: 
            	MIN: -9,223,372,036,854,775,808
            	MAX: 9,223,372,036,854,775,807
                unsigned MAX: 18,446,744,073,709,551,615
        Therefore...a long int will either be
        -2,147,483,648 and 2,147,483,647 for a 32-bit compiler
        or -9,223,372,036,854,775,808 and 
        9,223,372,036,854,775,807 for a 64-bit compiler, 
        whilst a long long int will just be 
        -9,223,372,036,854,775,808 and 
        9,223,372,036,854,775,807
        
        I hope this made sense!
