im trying to read a name from a file. its binary, so i cant use fin >> name; to get the different chars into a char[] is simple, but waht more does fin >> name add to the string? i use a space to signal that the name is finished, and this works fine! if i have fin = ifstream; char name[32]; fin >> name; func(name); //(char *text), it sends as char[12] (if 12 is the length of the word),not as a char[32] (as in the length of the name arrya)! my question is: what more then the chars does fin >> name; add to name[]? -Anders-Oredsson-Norway-

Figured it out by myselfe :-)

if we have a char text[12],
and we add "word" to it, we need to add a 0, and -51 for the rest, to make it the same as a normal string!

char text[12] = "word"
char text[12] =
''w'' ''o'' ''r'' ''d'' 0 -51 -51 -51 -51 -51 -51 -51
in char number format!

I case anyone wondered!

Just FYI, anything after the 0-character doesn''t matter, it doesn''t have to be -51, just ignore anything after the 0-character.

This is because strings in C and C++ are NUL terminated (NUL is the ascii character with value zero). so any function that manipulates or reads strings will only treat the data before the 0 as valid string-data. Anything after it is ignored.
