I have commands in a string something like:
string comm = "int x; cout << \"Digite um número\"; cin << x;";
My idea is to execute the commands that are in this string , having the result as if I had typed:
int x
cout << "Digite um número";
cin << x;
Is there any command to do this?
I thought of doing using in reader that identifies patterns and performs functions, but this would be very complicated, beyond what, I do not know how I would do to create the variables.
Generally speaking you do not have to, you have to create almost a compiler that does it for you. Of course you can use what you have ready as a basis to adapt.
Of course, if you restrict what you can use, it may be easier to do something simpler than a complete compiler, even though a C ++ compiler is very complicated, C ++ is considered the mainstream language more complicated to interpret.If you find complicated pattern matching , then forget about it, because it is much more complicated than that.
