c++ - Making a sequential list of files -

i have been stuck on problem while , can't seem find answer. i'm trying create multiple files same name different number @ end each time, have attempted @ first using

int seq_number = 1; while (seq_number < 10) { ofstream fsave; fsave.open("filename" + seq_number + ".txt"); fsave << "blablabla"; fsave.close(); seq_number = seq_number + 1; } 

but gives me strange result letters jumbled up, i'm not sure how works know doesn't.

i've looked online , found stringstream or sstream, , tried that, keeps giving me errors too,

string filename; filename = "character"; ostringstream s; s << filename << seq_number; filename(s.str()); fsave.open(filename + ".txt"); fsave << "blabla" fsave.close(;) 

but keep getting error:

no match call `(std::string) (std::basic_string, std::allocator >)'

i'm not sure how string stream works im working off of instinct, appreciate way possible, , think prefer doing without sstream, need way int , str , save filename string. unless know better way ;) guys

filename(s.str()); 

this wrong; not constructing new variable (filename constructed), want here assignment.

filename = s.str(); 

then,

fsave.open((filename + ".txt").c_str()); 

(although, if using c++11, change not necessary)

still, construct whole file name stream:

ostringstream s; s<<"character"<<seq_number<<".txt"; fsave.open(s.str.c_str()); 

i'm not sure how string stream works im working off of instinct

this bad idea, c++ quite minefield of bizarre syntax, segfaults , undefined behavior, going instinct leads disaster.

about errors get:

fsave.open("filename" + seq_number + ".txt"); 

this shouldn't compile, since summing integer const char * (thus moving "start of string"), , summing again const char *, not allowed @ all. maybe compile if this:

fsave.open("filename" + seq_number); 

but won't give required result - "filename" pointer (not c++ string), summing integer moves pointer of given offset.

in second snippet, instead, using object (filename) function, allowed if class overloads operator(); thus, compiler complains such operation not allowed on object.
