functions

[spra1323]

Can we write and call a function inside another function ,,,please explain this with an example ?? if multiple funcs ..how ?? what should be their return types ..??

[ultifinitus]

Write a function inside another? no.

Call a function from inside another? yes.

int function_two(){
return 2;
}
int function_one(){
return function_two();
} // returns 2

thanx ultifinitus ...
but, can we pass a function out put to another func..
eg.: func1(int func2, double func3)
{
\\ use func3 and func 2 return value here ...
}

is this possible ?? if yes ..please give some concrete example ...??

[ultifinitus]

Yes, it most certainly is, now do you want parameters with those parameters, or do you just want the function?

[spra1323]

can u explain ..both if possible ..please

int func1 (int a, int b)
{
a = func2(); //dunno what you want the functions to return, but whateva.
b = func3();
}

Err, or maybe this wasn't at all what you were asking for... I'm tired.

[spra1323]

thanx angelhoof ..
but i was looking for something like this :

int func1 (int func2(void), int func3(void) )
{
}

or is this same as what u had written ..
i donot know that ...

[ultifinitus]

It's called a function pointer. Google is your friend. You can look at functors if you want more.
