C++ - repeatedly using istringstream
- by Goffrey
I have a code for reading files with float numbers on line stored like this: "3.34|2.3409|1.0001|...|1.1|". I would like to read them using istringstream, but it doesn't work as I would expect:
string row;
string strNum;
istringstream separate; // textovy stream pro konverzi
while ( getline(file,row) ) {
separate.str(row); // = HERE is PROBLEM =
while( getline(separate, strNum, '|') ) { // using delimiter
flNum = strToFl(strNum); // my conversion
insertIntoMatrix(i,j,flNum); // some function
j++;
}
i++;
}
In marked point, row is copied into separate stream only first time. In next iteration it doesn't work and it does nothing. I expected it is possible to be used more times without constructing new istringstream object in every iteration.
