Thread: open file for different name everytime it runs

Code:

char id[10]="565656";
char buf1[100] = "\"C:\\testing\\script\\data\\";

strcat(buf1,id);
strcat(buf1,".txt\"");

cout << buf1 ;

ofstream filex(buf1);
filex << "testing";
filex.close();

while the output of buf1 is "C:\testing\script\data\565656.txt"
but the file have not created in the directory.

is the problem happened in ofstream filex(buf1)???
