C++ stoi()

In C++, the stoi() function is useful to change strings to integers. Basically, it only needs one parameter, and it is like stoi(something).

Example:

#include <iostream>
using namespace std;

int main()
{
    string x;
    cin >> x;
    cout << stoi(x) + 1; // prints the input + 1
}

Example Output:

>>> 1
<<< 2

And that’s all! In short, stoi() is a function that converts strings into integers.
