i was working on an assignment and we usually declare the constructor in this example

class test
{
public:
test();

then the rest of the stuff obviously

i noticed a program doing it this way and wasn't sure what its doing

class test
{
public:
test() {}

no semicolon and the open/close braces... what is the diff or why is it used?

The difference is that in the first example, the constructor is just declared. You also have to define it in your cpp file. In the other example, with the braces, the definition is done, what is called, "inline". Search on google for inlineing code in C++ and you will get some good explanations.

how would i change this which is inline then to the regular declaration of doctor();

class doctor
{
public:
doctor(){}


doctor(const char *n)
{
strcpy(name,n);
for(int col=0;col<41;col++)
appointments[col]=NULL;
}

};
just move the
doctor(const char *n) stuff outside the close class and declare it as doctor::doctor(const char *n){
stuff inside
}

??

nevermind i believe i figured it out, thanks for the information, made it clear what the program was trying to do, so i was able to change it to how i wanted it

appreciate the help!

yup, some code tags would make members more helpful.
