How to use stoi?

Question

I want to use a switch statement in C++ to check for user input, however, the input I want the switch to check is a string. I've read that by converting strings into integers (e.g. by using stoi) it is possible to use a switch statement to perform this task. Can someone show me an example of a conversion string -> integer done with stoi?

string x = "10"
int number = atoi(x.c_str())
