(C++) auto create object / variable

Question

i want to create variable / object with a specific pattern. example in python, i can write something like:
num = 0
for (i in range(10)):
auto = "var%d = %d" %(num, num)
exec(auto)
num+=1

so i have 10 variable now. unfortunately, c++ doesnt have a function like enum or exec. any idea? im stuck here.

Answer 1

You can do it with arrays, but the variable name do not really change
You can allocate memory so that you have more space (like more integers) usable during runtime

Answer 2

you can overload string operator '%', but the problem will reside in the right part of the code.
If num is not a primitive type (can be a wrapper of a primitive type), you'll have to override the ',' operator to store all the variables (maybe return a std::tuple) then use it with the operator '%' you did with the tuple you used. If you want to keep track of num so that it can be changed, use references

Answer 3

I read back the question, and indeed I made a mistake. You can't create variable names at runtime (you can though at compile time)

Answer 4

@baptiste
im not understand. your point is, i need to overload string operator?

Answer 5

yeah. what i mean is create variable at runtime. i hope i can find the answer :)
