unsigned long int	    at least 4	                         %lu
unsigned long long int	at least 8	                         %llu

long double	      at least 10, usually 12 or 16	             %Lf

Example 2: how maany bytes in an int in C

[8-bit] signed char: -127 to 127
 [8-bit] unsigned char: 0 to 255
 [16-bit]signed short: -32767 to 32767
 [16-bit]unsigned short: 0 to 65535
 [32-bit]signed long: -2147483647 to 2147483647
 [32-bit]unsigned long: 0 to 4294967295
 [64-bit]signed long long: -9223372036854775807 to 9223372036854775807
 [64-bit]unsigned long long: 0 to 18446744073709551615

Example 3: 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!

Example 4: what is float in c

float: It is used to store decimal numbers (numbers with floating point value) with single precision. double: It is used to store decimal numbers (numbers with floating point value) with double precision.

Example 5: what is float in c

A float is a number with a decimal point.
