Question

i have file like this

"a",205    
"b",214    
"c",223    
""",13

and i need to parse it
i read line by line to str and i have to convert second character from string to integer, but when it comes to quote <“> character it throws an exception string subscript out of range.

std::string STRING;
std::ifstream infile;
std::vector < std::string > tokens;
infile.open (Filename);

unsigned int x; 
while(! infile.eof()) 
{
    std::getline(infile,STRING); 
    tokens = Utility::splitString(STRING,',');//array of tokens
    x = (unsigned int)tokens[0][1];//convert first tokens,second character to uint
}

I think it is something with escape sequence.

Answer 1

1. tokens[0][1] gets the second character of the first string, which is out of range.

2. The type cast is not the way to convert. use atoi().
