Reading in a char from a string

xtunacanx (1)
Here's the problem. In getWord(string&); I'm trying to read in a character, determine if its a nonblank or blank character and from then beginning of the string line to the next blank character (excluding nonblank characters) should equal a word. But it keeps going into an infinite loop.

Here's the output:

Number of non-blank characters in the file: 6

(infinite loop..........)

There is no function named getLine that takes a reference to a string. Did you mean getWord(string &) ? In that case, you *could* just do this to get each individual word:
1
2
3
4
5
6
 
std::istringstream linestream (line);
std::string word;
while(linestream >> word)
{
    //process word, it will already have spaces trimmed
}
