pointer

[ajunboys]

known char *cts = "hello, girl!". so what is the *cts, cts? Why?

[weaknessforcats]

Look at this in C:

int x;
 

this says that the variable x is an int.
Then try:

int x,y;
 

This says the variable x and y are ints.
OK so far. Now try:

int x,y,*z;

This says that the variables x,y and *z are ints.
OK. Now put these definitions on separate lines:

int x;
int y;
int *z;

Finally, since whitespace doesn't count, you can move the *:

int x;
int y;
int* z;

Nothing has changed. x is an int. y is an int. and *z is an int.

With respect to *z, the variable z is called a pointer. A pointer is to contain an address. In this case z must contain the address of an int.

If you display z you see the address of the int. If you display *z you see the int.

cts is a just pointer to string.
