c++ - Use an array declared inside an if condition elsewhere

Question

I declared an array depending upon a randomly generated number. Now i know we can't use an array generated inside an if block anywhere else but i heared there are ways like dynamic memory allocation & vectors etc? any help on that?

    srand(time(0));
int num=rand() % 6 + 1;

if(num==1)
char word[6] = {'b','a','t','m','a','n'};

if(num==2)
char word[6]={'k','i','l','l','e','r'};

if(num==3)
char word[6]={'b','e','a','u','t','y'};

Answer 1

From what you show, you might use:

srand(time(0)); // Called only once, probably in main

char words[3][6] { // Possibly const // Possibly std::vector<std::string>
    {'b','a','t','m','a','n'},
    {'k','i','l','l','e','r'},
    {'b','e','a','u','t','y'}
};

int num = rand() % 3;
auto& word = words[num]; // char (&word)[6] = words[num];
