2.23 C++ How to Program (8th Edition) By Paul Deitel, Harvey Deitel

(Largest and Smallest Integers) Write a program that reads in five integers and determines and prints the largest and the smallest integers in the group. Use only the programming techniques you learned in this chapter.

Solution:

 
#include <iostream>
using std::cin;
using std::cout;
using std::endl;
 
int main()
{
  int num1, num2, num3, num4, num5;
 
  cout << "Enter the five integers: " << endl;
  cin >> num1;
  cin >> num2;
  cin >> num3;
  cin >> num4;
  cin >> num5;
 
    cout << "The entered integers: " << num1 << ", " << num2 << ", " << num3 << ", " << num4 << ", " << num5 << ".\n";
    {
  if(num1 < num2)
  if(num1 < num3)
   if(num1 < num4)
    if(num1 < num5)
       cout << "Smallest is " << num1 << endl;
  if(num1 > num2)
  if(num2 < num3)
   if(num2 < num4)
    if(num2 < num5)
       cout << "Smallest is " << num2 << endl;
  if(num3 < num2)
  if(num3 < num1)
   if(num3 < num4)
    if(num3 < num5)
       cout << "Smallest is " << num3 << endl;
  if(num5 < num2)
  if(num5 < num3)
   if(num5 < num4)
    if(num5 < num1)
       cout << "Smallest is " << num4 << endl;
  if(num4 < num2)
  if(num4 < num3)
   if(num4 < num1)
    if(num4 < num5)
       cout << "Smallest is " << num5 << endl;
}
{
 
  if(num1 > num2)
  if(num1 > num3)
   if(num1 > num4)
    if(num1 > num5)
       cout << "Largest is " << num1 << endl;
  if(num2 > num1)
  if(num2 > num3)
   if(num2 > num4)
    if(num2 > num5)
       cout << "Largest is " << num2 << endl;
  if(num3 > num2)
  if(num3 > num1)
   if(num3 > num4)
    if(num3 > num5)
       cout << "Largest is " << num3 << endl;
  if(num4 > num2)
  if(num4 > num3)
   if(num4 > num1)
    if(num4 > num5)
       cout << "Largest is " << num4 << endl;
  if(num5 > num2)
  if(num5 > num3)
   if(num5 > num4)
    if(num5 > num1)
       cout << "Largest is " << num5 << endl;
     }
 
   return 0;
