Oceans in millimeters program

grider67 (28)
I'm trying to write a program to export an ocean's level using 1.5 millimeters as the current variable. Then I need to show what the ocean's level will be at 5, 7, and 10 years.

I know I'm missing something. I need help please.

  // If the ocean’s level is currently rising at about 1.5 millimeters per year
// what will the ocean's level in 5 years
// what will the ocean's level in 7 years
// what will the ocean's level in 10 years

#include <iostream>

using namespace std;

int main()
{
	int millimeters; // variable current ocean's level

	millimeters = 1.5; // store 1.5 in the variable millimeters

	cout << "The ocean's level in 5 years." << endl;

	cout << "(1.5) * 5 = " << 1.5 * 5 << endl;

	cout << "The ocean's level in 7 years." << endl;

	cout << "(1.5) * 7 = " << 1.5 * 7 << endl;

	cout << "The ocean's level in 10 years." << endl;

	cout << "(1.5) * 10 = " << 1.5 * 10 << endl;

	return 0;
}

1.5 is a floating point number so use a float instead of an int when declaring millimeters. An int can only store integers (whole numbers).

float millimeters; // variable current ocean's level
millimeters = 1.5; // store 1.5 in the variable millimeters


Then when you use your cout's you can use the following to supply the numbers to the terminal.

1

cout << "(1.5) * 5 = "<< millimeters * 5 << endl;
...


If your compiler is C11 compliant or later, you could possibly use std::to_string(millimeters) to remove all hard coded 1.5 values in your cout statements, and thus can change to any number of millimeters a year without having to change a lot of code.

Please forgive me for incorrect info. I was answering multiple posts while getting gas and got them crossed, the following code has been corrected.
Example:

 
 
cout << "(" << millimeters  << ") * 5 = " << millimeters * 5 << endl;

It looks like your program executed faster than you were able to read the output. It looks like you may be using Visual Studio, in which case try pressing ctrl + F5.

JLBorges code of

std::cout << "\npress enter to quit program... " ;
std::cin.get() ; // keep the console open till user presses enter


Is another way to keep the command window open until you're ready to exit.

The messages

...

are not errors.

To keep the console open, add these two lines right at the end of main, and build and run the program again.

Here is the final product. Thanks for the help.

// If the ocean’s level is currently rising at about 1.5 millimeters per year
// what will the ocean's level in 5 years
// what will the ocean's level in 7 years
// what will the ocean's level in 10 years
