我的项目中从 const char 到 int 错误的无效转换

Question

#include <iostream>

using namespace std;

int
main ()
{
  int number1, number2, sumatotala, choose, add, multiply;
  add = "add";
  multiply = "multiply";
  
  cin>>choose;
  cin>>number1;
  cin>>number2;
  
  if(choose = add) cout<<number1+number2;
  if(choose = multiply) cout<<number1*number2;

  return 0;
}

This is my code and I have the next error. main.cpp:17:9: error: invalid conversion from 'const char*' to 'int' [-fpermissive] add = "add"; ^~~~~ main.cpp:18:14: error: invalid conversion from 'const char*' to 'int' [-fpermissive] multiply = "multiply"; ^~~~~~~~~~

I want to make a little program that lets u choose multiply or add and based on your decision multiply or add the 2 numbers. I don't code that well and if someone could help me I would be very gratefull.

Answer 1

add = "add";            
multiply = "multiply";

Here you need to either use numbers as values (because these are integer variables) or if you need them as strings, you have to remove them from the above line and write them like this:

std::string add = "add";
std::string multiply = "multiply";
