copying values from an array to an array in a function.

Is it possible for me to copy an array of string values which is declared in my main method to a function which is located in a class file?

Sure. Are you using char* or std::string?

i`m using std::string


for more info here are my code snippets

 dataComb=getData.toString()+data.toString();// i combined the values of string of x,y cordinates and sunType etc
 dataStore[counter]=dataComb;// i stored them here 

as you can see i am trying to copy the values of dataStore[] into my function computeCivicIndex()

which is

float locationData::computeCivicIndex(string dataStore [])
{
	int counter=0;
    for(int i=0;i<=counter;i++);
    dataStore[i]=dataStore[i];


}

i tried doing it in this way but it returns me with a error which says
locationData.cpp: In member function ‘float locationData::computeCivicIndex(std::string*)’:
locationData.cpp:101: error: name lookup of ‘i’ changed for ISO ‘for’ scoping
locationData.cpp:101: note: (if you use ‘-fpermissive’ G++ will allow the code to compile)

may i know the correct way of doing this?
i am supposed to take in the values from the array and used it in the computation process in computeCivicIndex() method

That error is due to the the ; on line 4. Although assigning thing to itself is no good anyway. To make a copy of array arr of type T and length len do

T* copy = new T[len];
for(int i = 0; i < len; i++) copy[i] = arr[i];

Don't forget to delete copy later.
Although if you use std::vector instead of an array, the copy will be made automatically when passed by value or on plain assignment. If you ever want to avoid copy, pass by reference.
