Hey guys, I want to do the following and I have no idea how to do this.

Code:
```Function area_regular_hexagon

Pass In: side

Calculate – side times 3 times the square root of 0.75

Pass Out: the calculation

Endfuction```
I need to write the C++ code to do the these specific task function. Can someone help me with this?

2. And what part of it are you having trouble with? What you have to do couldn't be worded more clearly. Post your best effort.

3. what's not to know? they tell you, practically line by line, what the function is supposed to be.

do you know how to create a function?

4. Honestly, I do't know at all how to do this. It's a problem related to a chapter, but nothing is explained about it in that chapter. Don't really get the pass in/ pass out.

5. Here it goes... that's what I got.

Code:
```#include <iostream>
#include <cmath>
using namespace std;

// Function Prototypes
void get_data(void);
void process_data(void);
void show_results(void);
void pause(void);

// Variables

double  side_1;

//******************************************************
// main
//******************************************************

int main(void)
{
get_data();
process_data();
show_results();

return 0;
}

// Input
void get_data(void)
{
cout << "\nEnter the total side_1 in the hexagon --->: ";
cin >> side_1;

return;
}
// Process
void process_data(void)
{
answer = side_1 * 3 * sqrt(0.75);

return;
}

//Output

void show_results(void)
{
cout << "\n";
cout << "\nThe area of the hexagon is---->: ";
pause();
return;
}

//******************************************************
// pause
//******************************************************

void pause(void)
{
cout << "\n\n";
system("PAUSE");
cout << "\n\n";
return;
}

//******************************************************
// End of Program
//******************************************************```
But that can't be it. It's supposed to be a short answer.

6. It is a short answer. Don't count all the cin/cout fluff.

Oh, and "pass in" and "pass out" means parameters and return values, not global variables.

7. ok thank you guys. Then I will do that.
