Use fstream .get to get more then one char

How can I use fstream .get to get more then one char?

Loop it.

Or you could use the getline function.
http://www.cplusplus.com/ref/iostrea...m/getline.html
Or if you are using strings
http://www.cppreference.com/cppstring/getline.html

Take a look at get()

I am using get but it is only leting me get one char at a time

Code:

---

while (fin.get(ch))
  {
   
      //Image file name 
      if (ch == 'F' )
      {
            fin >> imageName;
           
            }

---

It only lets me compare one char. what I would like to do is compare a string but not sure how to do that.

Use getline like Enahs said.

You can also use fin >> like you did with imageName, just read into a string variable. It will read up until the next whitespace, whereas getline will read until the next newline.

I am using

Code:

---

string s;
  int flt;
   
  while (getline(fin , s))
  {
   
      //Image file name 
      if (s == "F" )
      {
            fin >> imageName;
           
            }
      if (s == "I")
      {
        fin >> flt;
        ImRight = flt;
      }

---

It wont get any data from the text file. Any one know why not?

What does the file data look like (especially the first few lines)?

fin.getline(fin , s);

getline is a member, similarly to get.

ok well the file looks like this

F AnimBall.bmp
L 1
I 93
T 41
O 125
R 0
G 255
B 0
# 14
D 150
W 900
M 87

until I can get more then one char.

second if I use

Code:

---

while (fin.getline(fin , s))

---

I get error
no matching function for call to `std::basic_ifstream<char, std::char_traits<char> >::getline(std::basic_ifstream<char, std::char_traits<char> >&, std::string&)'

Don't use fin.getline(fin, s). That is wrong (getline is a member if you are using with C style strings, but you are using C++ strings, so you had it correct).

The problem is that getline reads in the entire line. But since F and AnimBall.bmp are on the same line, one call to getline reads them both.

Use fin >> s to read into the string instead of getline.
