Question

I'm having trouble correctly putting this function into my code.

Answer 1

Pausing a Command Prompt Program

One of the nuisances of C++ compilers, such as our recommended DevC++ compiler, is how they handle simple "console applications". These are programs like the ones demonstrated in our textbook and like the ones we will write for homework. Console applications use the Command Prompt window to interact with the user, using textual inputs and outputs. When we compile and create a console application, the compiler creates an executable .EXE file. When we run that program, a Command Prompt window opens for the duration of the program.

Answer 2

And that's the problem. When the program is over, the compiler chooses to close the Command Prompt window, which is no longer needed. From out point of view, the window opens momentarily and then disappears before we can view its results. Fortunately, there are simple ways to hold the window open until we have finished reviewing it. One way is to ask the user to enter a value from the keyboard and read that value in. right at the end of the program. The window will stay visible until the user completes the input.

Answer 3

A better way is to use the built-in function named "system". This function can accept an argument. When that argument is the text string "Pause", the system function will pause the program and display a message to the user. The program will only continue when the user hits any key. Here is an example:


#include <iostream>

#include <stdlib.h>

using namespace std;

int main( )
{
cout << "Demonstration of using System with the Pause option" << endl << endl;
system("Pause");
return 0;
}

Answer 4

This is what he said. This is what my program looks like.

As you can see, I'm having trouble correctly inserting the function. The rest of the lines built and compiled well.

Answer 6

At line 33 you have added two endl. Try removing one.

Answer 7

Well, that definitely fixed one thing wrong with it. It gave me this now.

error: 'system' was not declared in this scope|

Answer 9

Have you included the library 'stdlib.h'?

Answer 10

Explain?

Answer 11

Have you included this line in you code?
#include <stdlib.h>

Answer 12

No I have not let me try that now

Answer 13

That's why it didn't work. You haven't included that library.

Answer 14

I put it right under cout << "Your total is $" << total << endl;
and then put the remaining under the library and it didn't work
I'll show you how I set it up.

Answer 16

It should be loaded before the main() runs. Place it outside the function (in line 1 or 2).

Answer 17

fixed it!

Answer 18

Great!
