Help me to understand this error please

it is saying it could not convert when the data type in my ReadArray functions is istream and not int
here is the error:
1
2
3
4
5

10
intarray_c.cpp: In function `int main()':
intarray_c.cpp:81: could not convert `inF' to `int&'
intarrayfunctions.h:41: in passing argument 3 of `void ReadArray(int*, int, 
   int&, std::istream&)'
intarray_c.cpp:102: could not convert `inF' to `int&'
intarrayfunctions.h:41: in passing argument 3 of `void ReadArray(int*, int,

intarray_c.cpp:115: could not convert `inF' to `int&'
intarrayfunctions.h:41: in passing argument 3 of `void ReadArray(int*, int, 
   int&, std::istream&)'


here is part of the code where i call the function:

1
2
3
4
5
6
   ifstream Dat.open("data.in");
   ofstream ODat.open("data.out"); 
   ReadArray(fileData, 4, Dat);
   ReadArray(ID, 7, Dat);
   ReadArray(fileData, 5, Dat);
 


here is how i wrote my functions :

Do your function declarations in the header file match up with your definitions in the .cpp? It looks like it expects 4 arguments in the error message.
just checked the header file and that is the problem. thank you
