I am wondering about one thing.
I have code in a function that looks identical, except for one thing that differs depending on one variable.
I will use the example code:

if(value.first == "int")
{
   auto temp = value.second;
   return std::stoi(temp);
}
else if(value.first == "double")
{
   auto temp = value.second;
   return std::stod(temp);
}

… etc with other types.

This is, of course, only an insignificant fraction. Let’s say that we have a lot of such else ifs and code in each block even more.
Is it possible to create a single function that can be called with some argument, maybe some template? Which depending on the call will convert these std::sto* to the type it wants.
So as not to write many lines of code just one function.
