int fun1() const;
Will you please explain me where and why we need to use this? With example.

cin << input_number;

and not

cin >> input_number;

If not, what do you mean by the first case?

What exactly does it mean when you say the name of the function is a pointer?? A pointer to a variable, I understand, holds the address where the variable is stored. What is stored in the address that the name of the function points to?

Great tutorial. Thank you.

void foo()
{
printf(“Im foo”);
}

typedef void (*retType)();

retType FuncRetFuncPtr()
{
printf(“FuncRetFuncPtr calledn”);
return foo; //returning function pointer
}

main()
{
retType (*fptr)() = FuncRetFuncPtr;
void (*catchfoo)() = fptr(); //catchfoo-holds return val of FuncRetFuncPt

catchfoo(); //prints “im foo”. for confirmation :)
}

while(1)  {
    cout << "Write string: " ;
    getline(cin,input_string);
    cout << "Write number: ";
    cin << input_number;
...
}

Program should get input from user and make some actions, and then want again new input and again and again…In first loop everything works good, but in the second loop getline() dont read string, i get output:

Write string: Write number :

cin wants me to enter number , but getline was skipped, do u know why ?

Example:

typedef std::string (playerInfo::*memfuncptr)();
//Function prototype
memfuncptr strToMfptr(std::string &strInput);

So remember, typedefs are your friend. I still haven’t found out how to write the above without one, but am interested how it would look.
