Help with code

Question

trying to create a hi-lo guessing game , random function is not giving correct result

#include<iostream>
#include<ctime>
#include<cstdlib>
int getnumber()
{
int num;
while(1)
{
std::cin>>num;
if(std::cin.fail())
{
std::cin.clear();
std::cin.ignore(32767,'\n');
}
else
return num;
}
}
int ran_num()
{ int max(10),min(1);
std::srand(std::time(nullptr));
static const double fraction = 1.0 / (RAND_MAX + 1.0);
return min+(static_cast<int>((fraction*std::rand())*(max-min+1)));

}

bool playagain(char choice)
{
if(choice=='y'||choice=='Y')
return 1;
return 0;
}

void ischeck(int guessnum)
{

int usernum=ran_num();
std::cout<<usernum<<"\n";
if(usernum<guessnum)
{
std::cout<<"Guess is high"<<"\n";

}
else if(usernum>guessnum)
{
std::cout<<"Guess is low"<<"\n";

}
else if (usernum==guessnum)
std::cout<<"Congrats you guessed correct num"<<"\n";

}
int main()
{

for(int i=0;i<2;i++)
{
int n1=getnumber();
ischeck(n1);
}

}

Answer 1

what is the range you want to generate a random number in?

Answer 2

int max(10),min(0);

sorry for undocumented code, and i found the solution i.e we have to seed the srand(time(nullptr)) only once , because it will generate same value for same second
