2014/10/21 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> #include <stdlib.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)
              
              // come up with

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
