c++ - Printing one variable based on the contents of another variable -

i have function similar following takes integer parameter, , using integer want to access specific variable. of course, can casebash using case/switch statement, or if/else, far dirty , i'm guessing there must form of elegant solution.

static unsigned char frame1[] = {...}; static unsigned char frame2[] = {...}; /*...*/ static unsigned char frame30[] = {...};  int select_frame(int frame_number){   /* how can use frame_number select correct frame variable without case/switch, if @ all? */ } 

i feel though there potentially stringstream method (or similar), though i'm not sure. suggestions? i'm happy see solutions in either of c or c++.

edit: feel should note of these arrays have on 500 individual elements in them, , becomes little impractical combine them 1 giant array. if it's possible, i'm looking solution avoids method, though i'm considering it.

if want access 1 of frames based on integer, put frames array:

static unsigned char* frames[30];  frames[0] = (unsigned char*)strdup("first frame's char"); frames[1] = (unsigned char*)strdup("second frame's char"); 

then can directly , efficiently index frames[i].

in c++, more flexible approach use std::vector<std::string> (as long numbers contiguous) or std::map<int, std::string> (good if have numbers gaps, or want insert/erase single elements during runtime.

edit: helper function create string literal source code existing unsigned char arrays (off-the-top-of-my-head, tweaks may needed):

void f(std::ostream& os, unsigned char* p) {     os << '"';     ( ; *p; ++p)     {         if (*p < ' ' || *p >= 127)             os << '\\' << std::setw(3) << std::setfill('0') << std::oct << *p;         else if (*p == '\\')             os << "\\\\";         else             os << *p;     }     os << '"'; } 

then call f(frame1); f(frame2); etc...
