How do you search a std::string for a substring in C++?

Question

I\'m trying to parse a simple string in C++. I know the string contains some text with a colon, followed immediately by a space, then a number. I\'d like to extract just t

Answer 1

I can't just tokenize on the space (using sstream and <<) because the text in front of the colon may or may not have spaces in it.

Right, but you can use std::getline:

string not_number;
int number;
if (not (getline(cin, not_number, ':') and cin >> number)) {
    cerr << "No number found." << endl;
}
