help with file I/O on Crio ... unable to read file when fopen fails

[byteit101]

slightly off topic, but why are you using C style IO when C++ IO is available? In 09 we successfully used fstream IO with just "file.ext" style and "existingdir/file.ext" style open args

fstream file;
file.open("test.txt");


if (!file.is_open())
{printf("failed to open"); return false;}

file>>floatTest;


//and later we have something similar in order to write using fprintf
file<<floatTest;
