C - Opening a file inside a function using fopen

I am using Visual Studio 2005 (C \ C ++).

I pass the string to the function as a char array. I want to open the file passed as a parameter and use it. I know that my code works to some extent, because if I hardcode the file name as the first parameter, it works fine.

I notice that if you look at the value as an hour, the value includes the address in the direction of the string literal. I tried passing the file name as a pointer, but then it complains about type conversion using __w64. As I said, it works fine with "filename.txt" instead of fileName. I'm at a dead end.

void read(char fileName[50],int destArray[MAX_R][MAX_C],int demSize[2])
{
    int rows=0;
    int cols=0;
    int row=0;
    int col=0;
    FILE * f = fopen(fileName,"r");
...

Caller Function Code:

char in_filename[50];
int dem[MAX_R][MAX_C]; 
int dem_size[2];
get_user_input( in_filename);
read(in_filename, dem, dem_size );

In the watch that I added for the file name, the correct text appears, so the data is transferred.
