To convert a string to int (integer) in c++, we can use the stoi() function by passing a string as an argument.

Here is an example that converts the string pack to an integer 90.

#include <iostream>
#include <string>

using namespace std;

int main() {
 string pack = "90";

 int num1 = stoi(pack);
 cout << "string (\"" << pack << "\") is" << num1 << '\n';
}
