Question

Problem 5
Given a table of n integers and an integer k, make a program in C++ that:

a) Read n
b) Read the table of numbers.
c) Determine the number of elements in the table less than k
d) Determine the number of elements in the table equal to k
e) Determine the number of elements in the table greater than k
f) That displays the values found

Answer 1

#include <iostream>
#include<string>
using namespace std;

int main()
{
  int n = 0;
  int k = 0;
  cout<<"Enter number of elements\n";
  cin>>n;
  int values[n];
  cout<<"\nEnter elements\n";
  for(int i=0;i<n;i++)
  {
    cin>>values[i];
  }
  cout<<"Enter value of k\n";
  cin>>k;
  // to store values
  string lessThan;
  string greaterThan;
  string equalTo;
  // counters
  int less=0;
  int greater=0;
  int equal=0;
  for(int i=0;i<n;i++)
  {
    if(values[i]<k)
    {
      lessThan=lessThan+ " " +to_string(values[i]);
      less++;
    }
    else if(values[i]>k)
    {
      greaterThan=greaterThan+ " " +to_string(values[i]);   greater++;
    }
    else
    {
      equalTo=equalTo+ " " +to_string(values[i]); 
      equal++;     
    }
    
  }
  cout<<"Values in the table are ";
  for(int i=0;i<n;i++)
    {
      cout<<values[i]<<"\t";
  }
  cout<<"\n"<<less<<" values are less than "<<k<<"\t"<<lessThan;
  cout<<"\n"<<greater<<" values are greater than "<<k<<"\t"<<greaterThan;
  cout<<"\n"<<equal<<" values are equal to  "<<k<<"\t";
    return 0;
}
