I am trying to extract words from a text file and only want to get characters in the range between ! and ~. I know that the computer only understands numbers and so there are number representations of each character. To retrieve a single character from the the text file, I was thinking of doing something like
1 2 3 4 5 6 7 8 9 10 11 12
char c;
string word="";
cin.get(c);
while(c<! && c>~){ //to skip random control characters in the file
cin.get(c);
}
while (c>=! && c<=~){ //will add c to string word if within range
word+=c;
cin.get(c);
if(isspace(c)) // once hit a space, word is over
break;
}
I get an error that says
error: expected primary-expression before ')' token
and another error stating
error: label 'c' used but not defined
I thought c was defined as a char in line 1?
do I need to instead change the conditional for the while loop to
