I can't get the Largest and Smallest numbers using functions in C++.

#include<iostre am>
using namespace std;
int computeTotal();
int findSmallest();
int findLargest();
int main()
{
int n1,n2,n3,n4,n5, total,average,s mallest,largest ;

cout << "Number 1:";
cin >> n1;
cout << "Number 2:";
cin >> n2;
cout << "Number 3:";
cin >> n3;
cout << "Number 4:";
cin >> n4;
cout << "Number 5:";
cin >> n5;

total = n1 + n2 + n3 + n4 + n5;
cout << "Total:"<<total <<endl;

average = (n1 + n2 + n3 + n4 + n5)/5;
cout << "Average:"<<ave rage<<endl;


cout << "Smallest:"<<sm allest<<endl;

cout << "Largest :"<<largest<<en dl;

system("pause") ;
return 0;
}//end of main()
int computeTotal(in t n1,int n2,int n3,int n4,int n5)
{
int total=0;
total = n1+n2+n3+n4+n5;
cout << "Total :"<<total<<"\n" ;
return total;
}
int computeAverage( int n1,int n2,int n3,int n4,int n5)
{
int average;
average = (n1+n2+n3+n4+n5 )/5;
cout << " Average :"<<average<<"\ n";
return average;
}
int findSmallest(in t n1,int n2,int n3,int n4,int n5)
{
int smallest;

smallest = n1;

if(n2<smallest)
smallest = n2;
if(n3<smallest)
smallest = n3;
if(n4<smallest)
smallest = n4;
if(n5<smallest)
smallest = n5;

return smallest;
}
int findLargest(int n1,int n2,int n3,int n4,int n5)
{
int largest;
largest = n1;

if(n2>largest)
largest = n2;
if(n3>largest)
largest = n3;
if(n4>largest)
largest = n4;
if(n5>largest)
largest = n5;


return largest;
}

You display your largest and smallest numbers in main() but you never call the functions findSmallest and findLargest.

I'm new of C++ programming. if you know better ways that can help me display the exact value for largest and smallest. thanks ;)

There are better ways to display the largest and smallest numbers but, as you say, you are just beginning. The first requirement of a program is that it works. After that, it's just fine points. I would not worry about this but I would just continue on. You will get better as time goes by.

use this:
int n[4];
cout<<"Enter the four numbers:";
cin>>n[0]>>n[1]>>n[2]>>n[3];

int largest=a[0];
int smallest=a[3];//these are temporary.

for(int i=0;i<4;i++)
{
if(a[i]<smallest)
smallest=a[i];
if(a[i]>largest)
largest=a[i];
}
you may split it up into two loops if you want them as separate functions
