Key words of some "C"
Auto generally be omitted when EG: Auto Auto int char
do generally used in the while do
GOTO Skip
signed Marked for unsigned
BREAK used in the loop, switch statements,
double double precision
if if cycle
request byte sizeof (often analogy with strlen): in some objects of the string, differences exist omitted \ 0 end flag
void space (not require the use of the majority of the return value)
Case Switch statement appears often
eles if statements in the
data type int

static in " '' c" there are three usage {// Some arguments were not accurate
1. Local variables used in conjunction with the change life cycle, does not change the scope
2 in conjunction with global variables to change the scope
3. Call and extern another source file changing the scope
}

volateile less common, but seen it on behalf of a certain attainments c ha ha
enum enumeration enumeration constant
long data type
struct structure
while loop
const there is a saying, often for variable
extern call
the Register
Switch statement
continue statement continue in use
float single accuracy
return return value
typedef or redefined
dafault
for loop
short data type
union joint
