c++ functions

[poolet21]

Well the following program should be change each function for min / max and average I re-write it up to 10 time and isn't works.... I want a tip since my brain stops!!! :P DON"T post the full program answer just give me some details more in one function for example on min and I would let you know.....

#include <iostream>
using namespace std;
int main ()
{
int mn,mx;
const int Numb = 10;
double total;
int a[Numb];
double avg;
cout<<"Enter 10 values:";

for(int i=0;i<10;i++)
{
cout<< "\nEnter value: ";
cin>> a[i];

total = (a[0] + a[1] + a[2] +a[3] + a[4] + a[5] + a[6] + a[7] + a[8] +a[9] );

avg = total / 10;

}

mn=a[0];
mx=a[0];


for(int i=1;i<10;i++)
	{
		if(mn>a[i])
		{
			mn=a[i];
		}
		else if(mx<a[i])
		{
			mx = a[i];
		}
	}


cout<<"Maximum number is: "<< mx << endl;
cout<<"Minimum number is: "<< mn << endl;
cout<<"The average of numbers is: "<<avg<<endl;

return 0;

}

Please be aware that there are max & min -functions in C++ standard library. They are part of STL algorithms and you can use these functions after you have included this header file:

#include <algorithm>

Please see these links for info how to use them:
http://www.cplusplus.com/reference/algorithm/max/
http://www.cplusplus.com/reference/algorithm/min/

And if you are interested in seeing more useful algorithms like max & min, please check this link:

Prefer C++ standard library. Algorithms found there are made by professionals and are well optimized, meaning that they are fast for instance. Creating your average function is OK, though.
