Anyone know C++?

Can you give me a hand with this? I have no clue as to what I'm doing

     areaOfYard= FindArea(lengthOfYard,widthOfYard);

     std::cout << "\nYour yard is ";
     std::cout << areaOfYard;
     std::cout << " square feet\n\n";
     return 0;
 }

 int FindArea(int l, int w) // function definition
 {
      return l * w;
 }

There are plenty of C++ tutorials on the web if you need to learn it (I've got only a most basic understand of it, from partially porting the Mersenne twister pseudorandom number generator to assembly language for my HP48.)

I can help but I don't know what you are trying to do. What's the assignment?

[Technoid]

I did c++ for dos some 10 years ago and most of it is gone but the more I look at your code....

aparantly the program is suposed to compute the area of the "yard" specified in lenght and width.

Can you give me a hand with this? I have no clue as to what I'm doing

int addition (int a, int b)
{
  int r;
  r=a+b;
  return (r);
}

Uhm... why is the above included?

int main ()
{
  int z;
  z = addition (5,3);
  cout << "The result is " << z;
  return 0;
}

Ant this??

 int FindArea(int length, int width); //function prototype (declaration)

 int main()
 {
     int lengthOfYard;
     int widthOfYard;
     int areaOfYard;

     std::cout << "\nHow wide in feet is your yard? ";
     std::cin >> widthOfYard;
     std::cout << "\nHow long in feet is your yard? ";
     std::cin >> lengthOfYard;

     areaOfYard= FindArea(lengthOfYard,widthOfYard);

     std::cout << "\nYour yard is ";
     std::cout << areaOfYard;
     std::cout << " square feet\n\n";
     return 0;
 }

 int FindArea(int l, int w) // function definition
 {
      return l * w;
 }

uhm...I can't be sure that they havent included AI in the compailers but try this:

int FindArea(int length, int width); //function prototype (declaration)

 int main()
 {
     int l;
     int w;
     int areaOfYard;

     std::cout << "\nHow wide in feet is your yard? ";
     std::cin >> w;
     std::cout << "\nHow long in feet is your yard? ";
     std::cin >> l;

     areaOfYard= FindArea(int l, int w);

     std::cout << "\nYour yard is ";
     std::cout << areaOfYard;
     std::cout << " square feet\n\n";
     return 0;
 }

 int FindArea(int l, int w) // function definition
 {
      return l * w;
 }

not that I'd be surpriced if it still didnt compaile

Technoid, I'm not sure it your code will compile but it will certainly crash or return bogus values:

Following line "areaOfYard= FindArea(int l, int w);" should be "areaOfYard = FindArea(l, w);" you don't have to specify the data type.

Sorry about that guys, I was having a bad night last night (broke up with GF and couldn't quite think straight and having this due last night at midnight didnt help)

Basically what I'm trying to do is have two different fuctions.

The sq footage fuction works fine, as you can tell. The problem is that I can't get the fix value fuctions to work, I'm not sure how to show these together, ie have the sq footage fuction work, then goto the fix value fuction.

Here is the fixed value fuction:

int addition (int a, int b)
{
  int r;
  r=a+b;
  return (r);
}

int main ()
{
  int z;
  z = addition (5,3);
  cout << "The result is " << z;
  return 0;
}

Here is the sq footage fuction:

int FindArea(int length, int width); //function prototype (declaration)

 int main()
 {
     int lengthOfYard;
     int widthOfYard;
     int areaOfYard;

     std::cout << "\nHow wide in feet is your yard? ";
     std::cin >> widthOfYard;
     std::cout << "\nHow long in feet is your yard? ";
     std::cin >> lengthOfYard;

     areaOfYard= FindArea(lengthOfYard,widthOfYard);

     std::cout << "\nYour yard is ";
     std::cout << areaOfYard;
     std::cout << " square feet\n\n";
     return 0;
 }

 int FindArea(int l, int w) // function definition
 {
      return l * w;
 }

You mean something like this?

int FindArea(int length, int width); //function prototype (declaration)
int addition (int a, int b);

int main()
{
	int lengthOfYard;
	int widthOfYard;
	int areaOfYard;
	int z;

	std::cout << "\nHow wide in feet is your yard? ";
	std::cin >> widthOfYard;
	std::cout << "\nHow long in feet is your yard? ";
	std::cin >> lengthOfYard;

	areaOfYard= FindArea(lengthOfYard,widthOfYard);
	
	std::cout << "\nYour yard is " << areaOfYard << " square feet\n\n";

	z = addition (5,3);
	std::cout << "The result is " << z;
	return 0;
}

int addition (int a, int b)
{
	return (a + b);
}
int FindArea(int l, int w) // function definition
{
	return (l * w);
}

You do realize you have two Mains, right?

Or are these seperate files?

I'm still not clear on what you want to happen.
