c++ converting string to int

Question

//sLine is the string
for(int l = 0; l < sLine.length(); l++)
{
    string sNumber;
    if(sLine[l] == \'-\')
    {   
        sNumber.push_back(sLine[l]);
        sN         


        

Answer 1

That seems like a painful way to recreate the wheel. You'd be better off using a stringstream to parse this.

std::stringstream strm(sLine);
int num;
while(strm >> num)
{
    std::cout << num << std::endl;
}
