next time please put your code in the code tags.
im assuming your asking for something like this, everytime the program loops, n1/n2/n3 generate a random number for themselves, uses a for loop with if statements inside to determine the addition to the inside_count/outside_count, if those 2 numbers combined is greater than max_count then the loop will end.
Code:
#include <ctime>
#include <iomanip>
#include <iostream>
#include <random>
#include <string>
using namespace std;
int main()
{
srand(time(NULL));//make a random seed(i think its called a seed)
const int ubound = 99;//not needed
const int lbound = 10;//not needed
uniform_int_distribution<int> u(lbound, ubound);//not needed
int seed = rand();//not needed
//int seed = (int)time(nullptr);//not needed
//default_random_engine e(seed);//not needed
int outside_count = 0;
int inside_count = 0;
int loop_count = 0;
int max_count = 100;
int n1, n2, n3;
cout << "maxCount: " << max_count << endl << endl;
//run while inside_count + outside_count is less than max_count, increment loop_count on each run
for (; inside_count + outside_count < max_count; loop_count++)
{
//get random numbers for n1/n2/n3 on each run
n1 = rand();
n2 = rand();
n3 = rand();
cout << setw(3) << loop_count << ": (n1: " << n1 << ", n2: " << n2
<< ", n3: " << n3 << ") inside:" << setw(2) << inside_count << " outside: " << setw(2) << outside_count << endl << endl;
if (n2 > n1 && n2 < n3)//if n2 is greater than n1 and less than n3 increment inside_count by 1
inside_count += 1;
if (n2 < n1)//if n2 is less than n1 increment outside_count by 1
outside_count += 1;
if (n2 > n3)//if n2 is greater than n3 increment outside_count by 1
outside_count += 1;
}
system("pause");//with visual studio, press CTRL + F5 and the window will hold itself open without the need for this line
return 0;
}
