things commenly bought in cases water would be a data type each holds 6 packs of water but it onlys stores water so its an array 
 ie acesses 6 pack element 1
multi dimensional array 

sixpack[] []//commen means of accessing information one variable with 6 total addresses
go to spot in array and set loop put value in the array at its indicated address 
total = sum(scores,num); //function call sum is an argument that is passed the scores array providing the array and total size it is occupying 
sum will summ the scores return it and assign it 
summ will return int and assigined to total

call sum get result 
call highest get result
call lowest get result
wiht each call it is assigined name and parameters
first parameter to sum was an interger pointer 
avg is a float

main is completed 
define the first of the 4 functions 
the prototype above is a prototype that is going to be used in the future 
in the seocond half is a definition
int sum 
int n
in the fucnction has a diffrent name assigned to it and it is not the same 
whatever youc call it there are 2 sepreate variables being created 
/* run this program using the console pauser or add your own getch, system("pause") or input loop */


#include <stdio.h>

int   sum(int *,   int);
float average(int, int);
int sum(int*arr,int n)//with a function you can return more values

int main()
{
        int highest(int *, int);
        int lowest(int *, int);
	    int i,num=0// make sure to set to 0 because your going to add to it num is the running total
		int num = 4;
        int high, low;
        int scores[num];
        int i, total = 0;
        float avg;

        for (i = 0; i < num; i++)
        
        int sum(int*arr,int n)//with a function you can return more values
		
		arr [1]//add it to the array as another variable 
        
        num = num+arr[1]// to get the value back add 
        {
                return (0)

for any given input file, the file name files either into several assembler input files, or into one assembler input file; then each
assembler input file produces an object file, and linking combines all the object files (those
newly compiled, and those specified as input) into an executable file.
For any given input file, the file name suffix determines what kind of compilation is done:


gcc-E -o peed;some.p2-S read code to see what is readable and not

fhs
file system hierarchy stranded 

2s compliments
negative numbers start out with the negative numbers largest negative on top

%d signed int
%u unsigned int
%x/%x 4 bit hex values 
%c ascii characters
%hd is half of the interger 4 hd would be 2 
%hhd - half half signed int 
when using a 1 bit data type, unless specified it will be displayed as 4 bits 

its good to return a value  




variables- 73 interger
3.14
'c' character
"hello" array of char (aka "string")
"" double quotes is single '' is many 
"hello\0" 0 is a null character
memory addresses 0xdeadbeef 

variables 

ex. a user name

to make a variable declare the type (name)
type name = (0) type name = 0;so you can name it later

int 
char
%d means subsitute in a charachter
%x
