i am trying to open a file with ifstream and i want to use a string as the path (my program makes a string path). it will compile but it stays blank.
I know, it isn\'t the best idea to open a file constraining it to be placed in the same directory like the execute开发者_高级运维d module. But, there is a tool, I was ordered to program, with exact th
Can I inherit from ifstream and read the file from my derived class like this: #include <iostream>
File opens if I write the full path (full-path/roots.txt). File fails to open if I write the filename only (roots.txt)

I am reading a file like this: char string[256]; std::ifstream file( \"file.txt\" ); // open the level file.
Assume that I have an input as follows: N (X_1,Y_1) (X_2,Y_2) .... (X_N, Y_N) where N, X_i and Y开发者_高级运维_i are integers.
