Integer pointer

Tonni

• Apr 7th, 2007

Integer pointertypedef Is not the same as #define, meaning typedef does not make sure text is replaced before the compiler kicks in. It's a type definition, meaning everything declared as ptr will be an integer pointer.

kiran

In the following code p2 is an integer .from the code , tht we r using typedef to define integer pointer as ptr. so the code looks like tis int* p1,p2; whic is equivalent to int *p1,p2;hence p2 is an integer pointer.

Answer Question  Select Best Answer

No difference

Tonni

• Apr 7th, 2007

No difference. const either refers to the item on it's left, or if there is no item on the left, to the item on the right. So both lines declare s as a variable pointer to a constant character.

Answer Question  Select Best Answer

No difference

Tonni

• Apr 7th, 2007

Again nothing. Both mean that s is a constant pointer to a constant character.

You need not write #include, but at the time of compilation you need to compile with options which direct compiler to include files in the provided directory. in gcc it is done by -I option.
