Question

Say I have a string object called line which contains:

Number: 3423

and I want to do the following:

string keyword;
int number;
stringstream(line) >> keyword >> number;

But I only want to extract the number, and am not interested in the keyword.

is there a way of doing this without having to declare a string object?

Answer 1

You can use istream::ignore:

stringstream(line).ignore(line.size(), ' ') >> number;
