Hey, I am just learning functions. I was wondering if you could tell me why this piece of code is not implementing the 'values' function.

#include <iostream>
#include <windows.h>
#include <string>
#include <iomanip>
void values(float value1[11]);
using namespace std;
float value1[11], value2[11];
int main()
{
	cout << setiosflags(ios::fixed) << setprecision(2) << ios::showpoint;

	float value1[11], value2[11];
	char gauge[1], info;

	cout << "Welcome to my program, which converts celsius into fahrenheit,\nor fahrenheit into celsius.\n\n";
	do{
	cout << "**********\nCelsius - c\n**********\n\n";
	cout << "**********\nfahrenheit - f\n**********\n\n";
	cout << "Please enter the gauge that you would like to convert: ";
	cin >> info;
	if((info!='c')&&(info!='f'))
	{
		system("cls");
		cout << "You must enter 'c' or 'f'";
		system("pause");
		system("cls");
	}
	}while((info!='c')&&(info!='f'));
	system("cls");
	cout << "Please enter the temperature that you would like to see converted: ";
	cin >> value1[5]; 
	if(info == 'c')
	{
		gauge[0]='C';
		gauge[1]='F';
		values;
		for(int x=0;x<=10;x++)
			value2[x]=(value1[x]*9)/5+32;
	}
	else
	{
		gauge[0] = 'F';
		gauge[1] = 'C';
		values;
		for(int x=0;x<=10;x++)
			value2[x] = ((value1[x] - 32) * 5)/9;
	}
	system("cls");
	cout << setw(32) << gauge[0] << " |          | " << gauge[1] << endl; 
	cout << setw(45) << "|          |" << endl;
	for(int x=0;x<=4;x++)
		cout << setw(32) << value1[0+x] << "-|          |-" << value2[0+x] << endl;
	for(int x=0;x<=5;x++)
		cout << setw(32) << value1[5+x] << "-|**********|-" << value2[5+x] << endl; 
	cout << setw(45) << "|**********|" << endl; 
	cout << setw(46) << "/************\\" << endl; 
	cout << setw(47) << "/**************\\" << endl; 
	for(int x = 1; x<=5;x++)
		cout << setw(48) << "|****************|" << endl; 
	cout << setw(47) << "\\**************/" << endl; 
	cout << setw(46) << "\\************/" << endl; 

	return 0;
}
void values(float value1[11])
{
	for(int x=5;x>=1;x--)
		value1[x-1] = value1[x] + 1;
	for(int x=5;x<=9;x++)
		value1[x+1] = value1[x] - 1;
}

If lines 36 and 44 are supposed to be function calls, you need to put () after the function name. Please correct me if I am wrong, but I think thats the problem.

EDIT
You will need to put in a parameter as well. MAke sure it is the same data type as the one in the function definition.
Sorry I missed that at first glance/

Oh, ok. Ty. Sadly I have no clue what a parameter is..I shall look it up though. Thanks again for the information.

A parameter is what goes in the parentheses after a function call. The function call and the function definition must contain the same amount of parameters and they must be of corresponding data types. That explanation may be a little unclear. Look it uo online for more info.

Ah, ok. I tried this...but it still doesn't work:

......
	if(info == 'c')
	{
		gauge[0]='C';
		gauge[1]='F';
		values(float value1[11]);
		for(int x=0;x<=10;x++)
			value2[x]=(value1[x]*9)/5+32;
	}
	else
	{
		gauge[0] = 'F';
		gauge[1] = 'C';
		values(float value1[11]);
		for(int x=0;x<=10;x++)
			value2[x] = ((value1[x] - 32) * 5)/9;
	}

Are you getting compile errors or is it just not doing what you want it to do? If you are getting compiler errors, post them here.

Ok.

your function call should be :

values(value1);
