Thread: Project

Hi everyone, my name is Ryan. And I'm quite new to C++ Language. I'm looking for opinions on good basic projects involving C++ that I would be able to do. Just wanted some opinions, being that you guys have been giving opinions to other beginners.

Thanks in advance,
- Ryan

Just how new are you?

You could try this:
Write a program that displays the following menu:

1. Calculate for a Circle
2. Calculate for a Rectangle
3. Calculate for a Triangle
4. Quit

Please enter a choice (1-4):


Then after a choice of 1, 2, or 3 is made a from this main menu, a second menu is presented to ask whether they wish to calculate the circumference or the area for that shape.

After the user enters a choice of the shape and calculation desired the program should ask for the appropriate dimensions (a radius for a circle; length and width for a rectangle; Base and heighth for a triangle) and then it should display the desired vlaue and redisplay the main menu.

The program must validate the input and not allow any negative numbers as dimension values. It should also validate the input for the menu and only allow values 1, 2, 3, 4


If you're past doing that kind of stuff, then try it with classes instead of just procedural.

Thanks, for opinions.

Mario F. --> I have read the tutorials offered on this site. It was great help.

System_159 --> I have started a calculator project. Thank You.

One question is, I have Dev C++ 4.9.9.2 and it seems that the compiler doesn't take much coding. I mean, some code I try to enter in the program. And it simply doesn't know what it means. Any suggestions or places where I could get maybe a better compiler?

Thanks,

Also, in my coding for the calculator, I wish to divide each section (the sections being: Add, Substract, Multiplie and Divide) into cases.

Example:

Code:

#include <iostream>

using namespace std;

int main()
{
    cout<<"Welcome, what would you like to do?\n";
    cout<<"1- Add\n";
    cout<<"2- Substract\n";
    cout<<"3- Multiplie\n";
    cout<<"4- Divide\n";
    cin.get();
    cin.ignore();
{	
       case 0:
            EXIT();
            break;
       case 1:
            cout <<"Enter two numbers to add./n";
            cout <<">";
            cin >> C.num1;
            cout<<">"
            cin >> C.num2;
            C.equal = C.num1+C.num2;
            cout <<"Answer = " << C.equal<<end1;
            system("pause");
            RorQ();
            break;

Now that is just my add case. Now when I compile and run. It says: case label '0' not within a switch statement. Any help greatly appreciated. And keep in mind. I am new.

Thanks,
- Ryan

Agreed, but I even tested the compiler with a program that already works. And when I open it in Dev C++ and Compile & Run it. It says that there are errors in it. Yet I can open the program and use it.

Try a simple program like this:

Code:

#include <iostream>

using std::cout;
using std::endl;
using std::cin;

int main ( void )
{
   cout << "Hello World!" << endl;

   cin.get();

   return 0;
}

This is a very basic program in C++.

Somthing rather complex is:

Code:

#include <iostream>

using std::cout;

int main ( void )
{
   int total = 10;
   int *ptr = &totol;
   cout << *ptr << endl;
}

Try somthing simple, then work your way through. The tutorials on this site are a great help
