Dynamic structure array inside of a structure?

[lindsey laho]

Question:
How can I create a Structure that has a Dynamic Structure (array) inside of it using only the <new> and <iostream> libraries?

example:

struct fruit{
char name[100]
int seeds;
};
struct container{
fruit non_poisonous //unknown until later into the program how many fruit are poisonous must be declared as a dynamically arrayed structure
};

Please provide examples.(or full sample code)

I'm a little new to using <new> =).

Easiest would be to use a vector but that was not allowed :(

In container you store a pointer fruit*.

struct container{
	fruit* non_poisonous;
};

When you know how many fruits you want to store you can use the new keyword to create an array.

container c;
c.non_poisonous = new fruit[N]; // N is the number of fruits in the array 

You can now use non_poisonous similar to the array.

c.non_poisonous[0] .seeds = 5;
std::cout << c.non_poisonous[5].name;
...

When you don't going to use the array any more you can call delete c.non_poisonous to free the allocated memory.

THANK YOU!
You saved me from hours of endless trial and error.
I could've done it without structures inside structures, however there's so much in the actual program that everything would've taken ages to implement and even longer to actually use.
