Question

I have 20 digits and I would like to associate them with strings. Is there a faster way besides using a switch case statement to achieve this.

I need to convert an int to a corresponding string and the numbers aren’t necessarily packed. Some code in Qt as well might be useful?

Example: The following digits and strings are associated with each other,

1:   "Request System Info"

2:   "Change System Info"

10:  "Unkown Error"

Answer 1

easier way to use map

std::map<int, std::string> mymap;
mymap[1] = "foo";
mymap[10] = "bar";
// ...
int idx = 10;
std::string lookup = mymap[idx];
