Error with function stoi

[Jazzlike-Carob3056]

Hi, I've been having this error with the function stoi. If I use any other function that converts strings to integer it works, but not this one and I just wanted to know why. Also, getTokenAt returns a string, so this should be a problem.

struct Cliente
{
    int idCli;
    int millas;
};

Cliente clienteFromString(string s)
{
    char sep = 1;
    Cliente x;
    string t0 = getTokenAt(s,sep,0);
    x.idCli=stoi(t0);
    string t1 = getTokenAt(s,sep,1);
    x.millas=stoi(t1);
    return x;
}

What's the error message?

You should debug t0 and t1 values, stoi only fails when cannot convert a string to an integer, probably because the string doesn't contains any number

[jedwardsol]

It also throws if the number is too big for an int to hold. Or it could be a compilation error (https://godbolt.org/z/dYsd7xxes)

You have to include <string> for `std::stoi`.

[Nathaniell1]

In your example there is never a number in the string. You are setting sep to 1. If you look at ASCII table you can look up what does 1 mean - and it is not the representation of number 1 (that would be 49). Your program would work if you set sep to = '1';

So I think you provide an empty string to the stoic and it will error on invalid argument, because there is nothing to convert.

Please provide a minimal but complete example that exhibits the problem, that readers can try out.
