Write a program to sort two numbers using pointers?

Answer 1

This program works only on Microsoft compiler, people who are using another compilers will have to modify pointer initialization to

double vfirstNumber = 0.0;

double* firstNumber = &vfirstVariable;

...

double vsecondNumber = 0.0;

double* secondNumber = &vsecondNumber;

Or whatever you find is better.

#include <iostream>

using std::cin;

using std::cout;

using std::endl;

int main()

{

double* firstNumber = NULL;

cout << endl << "Enter first number: ";

cin >> *firstNumber;

double* secondNumber = NULL;

cout << endl << "Enter second number: ";

cin >> *secondNumber;

if (*firstNumber > *secondNumber)

{

cout << endl << *firstNumber << " > " << *secondNumber << endl;

}

else if (*firstNumber < *secondNumber)

{

cout << endl << *firstNumber << " < " << *secondNumber << endl;

}

else

{

cout << endl << *firstNumber << " = " << *secondNumber << endl;

}

system("PAUSE");

return 0;

}
