Question

Students with register number 1 to register number 50 are assigned to boys labelled as 1,2,3… 50 and students from register number 51 to register number hundred are assigned to girls labelled as 51, 52,…100.Execute various methods to display the set of students such that there is an alternating sequence of register numbers of boys and girls.

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;
}
