Creating a Basic Mathmatic Program in C++ - Hazzy - 2008-07-03

Well, I want to write a program to do a pretty simple function, using Visual C++ Microsoft 2008 Edition. However, first, I wanted to get the hang of what needs to be done to get any program to work, so I took one out of my book,

Code:
bool accept () 

{

    cout << "Do you want to proceed (y or n)?\b";

    char answer = 0;

    cin >> answer;

    switch (answer) {

        case 'y':

            return true;

        case 'n':

            return false;

        default:

            count << "I'll take that for a no. /n"

            return false;

    }

}

I typed it up in a new *.cpp file, and tried to debug. The debug option was grayed out, so I'm thinking I need to do more than just type up a file.
So, my question, how exactly do I get a simple program to work? D:
I have no idea how C++ works, lol, as this is my first real attempt at trying to make a program.

Please and thank you for your time. Big Grin

I tried compiling with the Command Prompt, that's what I got from the Help tab, and got these errors.

Code:
C:\Program Files\Microsoft Visual Studio 9.0\vc\bin>cl /EHsc BoolAccPro.cpp

BoolAccPro.cpp

BoolAccPro.cpp(3) : error C2065: 'cout' : undeclared identifier

BoolAccPro.cpp(6) : error C2065: 'cin' : undeclared identifier

BoolAccPro.cpp(14) : error C2065: 'count' : undeclared identifier

'return'

How do I declare the identifiers? ._.

Looks like you're missing

Code:
#include <iostream>

using namespace std;

You'll also need a main function.

maybe you should try to learn the most easiest program first. Here is the most simplest program that typed out "Hello World!"

#include <iostream.h>

main()
{
for(; Wink

{
cout << "Hello World! ";
}

}

or if i remember correctly it'll also work if you just have
#include <iostream.h>

main()
{
cout << "Hello World! ";
}

Here is the link to that program.

You would also need to go read the beginners book or maybe try C++ for dummies first. You can't just learn how to program without reading a book.

All programs have the following:

Quote:#include <stdio.h>
#include <stdlib.h>

int main()
{

system("pause");
return 0;
}

To declare the identifiers you do the following:

Quote:data_type variable_name;

Example:

int a;
float b;
char c;

If you want to make a simple math equation, like adding two numbers, here's an example:

Quote:#include <stdio.h>
#include <stdlib.h>

int main()
{
int a, b, c; //declaring the variables

printf("Insert the first number: "); //asking the user to input the number
scanf("%d", &a); //saving that number on the variable "a"

printf("Insert the second number: "); //see above
scanf("%d", &b); //see above

c=a+b; //self-explanatory.

printf("The result is: %d ", c); //the user will get the answer.

system("pause");
return 0;
}
