Hi,
why this does not work?
1 2 3 4
|
string file_name;
file_name = "/home/cristiano/matrix4.dat";
ifstream iFile;
iFile.open(file_name);
|
I think there is a problem with the variable type of file_name, but changing it from string to char still does not work.
1 2 3 4
|
char file_name;
file_name = "/home/cristiano/matrix4.dat";
ifstream iFile;
iFile.open(file_name);
|
Any help will be appreciated.
Thanks.

Do these compile?
The first one should fail on line 4 as it can't convert a std::string to const char*.
The second should fail on line 2 as it can't convert a char to a const char *.

Hi kbw,
this do not compile!(..I think you verified.)
I want to know how do I need to declare file_name... In the way I can pass it to iFile.open(file_name);
Can you think in some way?
Because I want to store the file name path in a variable and then use that variable to load the file.
