Difference Between Max and Min Numbers

Write a C++ program that accepts various numbers and computes the difference between the highest number and the lowest number. All input numbers should be real numbers between 0 and 1,000,000. The output (real numbers) may include an error of 0.01 or less.

C++ Exercises: Compute the difference between the highest number and the lowest number

Sample Solution:

C++ Code :

#include <iostream> // Header file for input/output stream operations
using namespace std;

int main()
{
    double num[52]; // Array to store up to 52 double numbers
    int c = 0; // Counter variable initialized to 0

    // Loop to read numbers from input and store them in the 'num' array
    while (cin >> num[c++]); // Reads numbers until invalid input is encountered and increments the counter 'c'

    sort(num, num + c - 1); // Sorting the array of numbers

    // Displaying the difference between the highest and lowest numbers entered
    cout << "Difference between the highest number and the lowest number: ";
    cout << num[c - 2] - num[0] << endl; // Output the difference between the highest and lowest numbers

    return 0; // Indicating successful completion of the program
}

Sample Output:

Sample Input: 2 5
Difference between the highest number and the lowest number: 3
