c++ string generator with print (cout)

so I wanna make a mini-quiz in c++ and it doesn't work, here is a code that i've tried

static const char alphanum[] =

"which one of this cities located in france"

cout << "1. paris 2. singapore 3. dubai 4. thailand";

"which one of this countries located in asia"

cout << "1. thailand 2. germany 3. spain 4. italy";

int stringLength = sizeof(alphanum) - 1;

char genRandom() // Random string generator function. {

return alphanum[rand() % stringLength];

}

int main()

{

srand(time(0));

for(int z=0; z < 1; z++)

{

    cout << genRandom();

}

example:

which one of this countries located in asia

1. thailand 2. germany 3. spain 4. italy
