Question

I want to generate 2 random numbers between 0 and 20

int one = rand() % 20;

it gives me 1 steady value i.e 1…

Am I missing something?

Answer 1

You have to give a seed to the random number.

srand( time(NULL) );
int num1 = rand() % count;


int num2 = rand() % count;

---

Random number between 1 and 20

int num = rand() % 20 ;

if( num == 0 )
    num += 2;

else if( num == 1 )
    ++num ;
