I took C class a year ago, now I'm taking assembly language class. It requires information from C as well. Now I need to review it.

Basic library or the header is
#include <stdio.h>
Declare variables:
int var: integer
double
float
char: store single characters in ASCII by ' ' or store an array by "".
For storing a string we can write
const char string[] = "I'm declaring a string";
array
Array and String
array of integer
int array_number[];
array of character
char array_char[];
type name[number of elements]={comma-separated values}
FAQ:
- What is the differences between i++ and ++i
i=1
j=++i (notice that ++ is before i so i = 2, and j=2)
k=i++ (notice that ++ is after i so k will keep the previous value of i, and i=2) - What does += mean?
for example
c=10
n=2
c += n (will output 12, n + c and return value to c)
