i read the file line by line
then store the lines in strings
but the space that is in the begin of line i want remove it before read the line and store it in the strings
Does the following make things clearer ?
// read a whole line ...
// the variable [B]line[/B] contains the whole line at this point
// insert code here to trim the leading whitespace
// insert code here to save the trimmed line
and when add this statment
,appear problem in the run (abnormal program termnation)
Here is one way to trim leading whitespace
string test_string = " test_string";
string ws = " \t";
// lookup the position of the first non-whitespace char, if any
std::string::size_type pos = test_string.find_first_not_of(ws);
if(std::string::npos == pos)
// string contains only whitespace
// drop the leading whitespace
cout << "[" << test_string << "]" << endl;
