Answer 1

#include <iostream>
#include <ctime>
#include <vector>
using namespace std;
int main()
{
  //first method 
  for(int i =1; i<=50; ++i)
   cout << i << ", "<< 50+i <<", ";
  //second method
  srand(time(NULL));
  vector<int> v;
  while (v.size()<100)
{
  if (v.size()%2==0)
  {
  int g=rand()%50+1;
  int count=0;
  for (int i =0; i<v.size(); ++i)
   if (v[i]==g)
     count++;
   if (count==0)
     v.push_back(g);
  }
  else
  {
  int g=rand()%50+51;
  int count=0;
  for (int i =0; i<v.size(); ++i)
   if (v[i]==g)
     count++;
   if (count==0)
     v.push_back(g);
  }
}
for (int j=0; j<v.size(); ++j)
  cout << v[j] <<",";
return 0;
