How to split a string in c++?

Question

C++ / C#

You need to split the string by sign. That is something like this:

#include <iostream>

int main()
{
    int a;
    std::cin >> a;
//пользователь ввел 23+56

Now the program must split the string by the + symbol, and understand which is the first number and which is the second.
Here is a python solution:

a = input()
a = a.split('+')
num1 = a[0]
num2 = num[1]
