how to import text file into structs C++ - c++

Question

I'm trying to import data from a text file into structs for use as i don't really want to import them into seperate arrays.
I keep getting "error: expected primary-expression before '[' token" on each getline, i'm terrible at C++ and basically using what C skills i have to try and make sense of this. What am i doing wrong?
#include <stdio.h>
#include<fstream>
#include <cstdlib>
#include <iostream>
#include "Ladybird.h"
using namespace std;
typedef struct managerImport{
int gridSizeA;
int gridSizeB;
int aphidCount;
int aphidPos;
int ladyCount;
int ladyPos;
struct managerImport *next;
};
void importData(managerImport[]){
ifstream manager;
manager.open("Manager.txt");
if (!manager.fail()){
//loops the 2d array
for (int i = 0; i < 1; i++)
{
getline(manager, managerImport[i].gridSizeA, managerImport[i].gridSizeB);
}
//loop the lady bird count
for (int i = 1; i < 2; i++)
{
getline(manager, managerImport[i].ladyCount);
}
//loops the lady bird coordinates
for (int i = 2; i < 10; i++)
{
getline(manager, managerImport[i].ladyPos);
}
for (int i = 10; i < 11; i++)
{
getline(manager, managerImport[i].aphidCount);
}
//loops the lady bird coordinates
for (int i = 11; i < 19; i++)
{
getline(manager, managerImport[i].aphidPos);
}
}
manager.close();
}
int main() {
//importing the manager text file
importData;
}

Answer 1

Did you name the argument in the function?
void importData(managerImport[]) just says you have a function importData that takes an array of type managerImport (your struct).
Edited for clarification:
Imagine I write this code:
int increment(int) { return int+1; }
What I've done is hand the compiler a function that takes an argument "int". Is "int" a type or the name of my argument? This obviously won't compile since the argument has to have both a type and a name (so even if I want want to name my argument "int" (not advised), I still need to supply a type which says what "int" actually is (type-wise). Is it a long, a string, an unsigned char? Assuming I meant to actually accept an int, add 1, and return the incremented value (an int), this is what I should have written:
int increment(int i) { return i+1; }
So, in your case, you have:
void importData(managerImport[]) { ... }
Obviously, you're meaning to accept an array of managerImport, but you haven't given that array a name. Try this:
void importData(managerImport foo[]) { .. }
Also, unless you really need a c-array, you might try using a vector or an C++ array (std::array).

Answer 2

The function getline does not translate text into integers. It simply copies text without translations.
for (int i = 0; i < 1; i++)
{
getline(manager, managerImport[i].gridSizeA, managerImport[i].gridSizeB);
}
Your getline function call translates to getline(stream, int, int);.
You will need to either use:
manager >> managerImport[i].gridSizeA >> managerImport[i].gridSizeB;
or read in as string and parse out of the string.
