Topics

If/Else statement

Description

  

Write a program that determines the larger of the two numbers provided by the user. The program asks the user to enter a number. Then it asks the user to enter another but a different number. Then, it determines the larger of the two numbers and displays it to the user. (If the user happens to enter the two numbers the same, the program may report either of the two numbers as larger.)

Requirements

Do this assignment using an If/Else statement.

  

Testing

Perform the test run 1 and the test run 2 below with the data shown.

(User input is shown in bold).

(If your output does not contain a decimal point but have the same values, it's OK.)

Test Run 1

Enter the First Number

12.0

Enter a Different Second Number

15.0

First number: 12.0

Second number: 15.0

Larger number: 15.0

Test Run 2

Enter the First Number

15.0

Enter a Different Second Number

12.0

First number: 15.0

Second number: 12.0

Larger number: 15.0

The output of the test runs.

Sample Code

//declare variables

double n1, n2, larger;

//write code below to input two numbers from the user in variables n1, n2

// The following code determines which number is largest among n1 or n2

// and stores the largest number in variable largest

if (n1 >= n2) {

            larger = n1;

}

else {

            larger = n2;

}

//Alternative format:

//When there is a single statement inside a pair of braces as above,

//the pair of braces can be skipped as below:

if (n1 >= n2)

            larger = n1;

else

            larger = n2;

Answer 1

Since you have not provided the language of your preference, I am providing the code in C++.

CODE

#include <iostream>

using namespace std;

int main() {

//declare variables

double n1, n2, larger;

cout << "Enter the First Number: ";

cin >> n1;

cout << "Enter a Different Second Number: ";

cin >> n2;

// The following code determines which number is largest among n1 or n2

// and stores the largest number in variable largest

if (n1 >= n2) {

larger = n1;

}

else {

larger = n2;

}

cout << "First number: " << n1 << endl;

cout << "Second number: " << n2 << endl;

cout << "Larger number: " << larger << endl;

}
