Question

Write a C++ program that declares three variables minNum, midNum and maxNum
to receive three integers read from the keyboard. The inputs are unsorted and can be
read into the three variables in any order, for example, the first read number in
minNum may not be the smallest. However, your program should then sort the three
numbers to ensure minNum ≤ midNum ≤ maxNum and display them in this order.

Answer 1

#include<iostream>
using namespace std;

void f(float &x, float &y){
float t;
t = x;
x = y;
y=t;
}

void main(){
float minNum,midNum,maxNum;
cout <<"Enter minNum: ";
cin>>minNum;
cout <<"Enter midNum: ";
cin>>midNum;
cout <<"Enter maxNum: " ;
cin>>maxNum;

if(minNum>midNum)f(minNum,midNum);
if(minNum>maxNum)f(minNum,maxNum);
if(midNum>maxNum)f(midNum,maxNum);

cout <<"\nSorting...\n minNum : "<<minNum; &
cout <<"\n midNum : "<<midNum;
cout <<"\n maxNum : "<<maxNum <<"\n\n";

system("PAUSE");
}
