Initially seems like very trivial problem.
i have input: string a, string b.
b only takes two values, “string” and “int”.
i want to declare a new variable var0 with a type that corresponds to b.

how to implement the logic.

i thought this function would work but it wont.

auto varx(std::string a, std::string b){  
    if(b == "int") return std::stoi(a);  
    return a;  
}  

e.g. auto var0 = varx(“43”, “int”); should set var0 as int var0 = 43;

I have seen union or variant in discussions but not sure how to implement.
