Structure pointer to function? - c++

Question

I am trying to pass a structure I created in a function to another function so basically what im trying to do is dynamically create the amount of structures needed the amount of structures is in a text file so in the text file there would be a number like 5 and and 5 data sets. I want to pass the structures I created in my function to another function. I started programming a few months ago so forgive me if there is a simple solution or if this question has been asked.
struct graph
{
int Max,Min,index;
double dataArray[300];
};
void readfile()
{
int amount;
char tmpSTR,nmbrGraph;
ifstream myFile("data1.txt",ios::in);
myFile>>amount;
myFile>>tmpSTR;
myFile>>nmbrGraph;
graph* Data = new graph[amount];
for(int j=0;j<nmbrGraph;j++)
{
for(int i=0;i<299;i++)
myFile>>Data[j].dataArray[i];
}
//hOW WOULD I PASS THE STRUCTURE "DATA" TO THE FUNCTION anotherFunction?
}
void anotherFunction()
{
for(int i = 0;i<300;i++)
cout<<Data[scroll].dataArray[i])<<endl; /*Error here! scroll being an
integer declared globally*/
}

Answer 1

Pass the graph* pointer by value or reference to anotherFunction as an argument. Also, it is important to include the number items, as that was determined by reading the file and not knowable beforehand.
// by value
void anotherFunction(graph* Data, int amount);
// by reference
void anotherFunction(graph*& Data, int amount);
