excuse me sir,can you help me with my c++ problem

Code:

//calculate bandwidth using maximum-minimum
#include<iostream>
using namespace std;
int maximumValue( int , int , int , int , int);//function prototype
int minimumValue( int , int , int , int , int );//function prototype
int bandwidth;
int main()
{
int v , w , x , y , z ;
cout<<" enter five integers "<<"\n\n";
cin>> v >> w >> x >> y >> z ;
cout<<"\n\n"<<" the maximum value is " <<maximumValue(v,w,x,y,z)<<"\n\n";
cout<<"\n\n"<<" the minumum value is " <<minimumValue(v,w,x,y,z)<<"\n\n";
cout<<"\n\n"<<" the bandwidth is "<<bandwidth<<maximumValue-minimumValue<<"\n\n";
cout<<endl;
return 0;
system("pause");
}
int maximumValue( int a , int b , int c , int d , int e)
{
if (a>b && a>c && a>d && a>e)
return a;
else if (b>a && b>c && b>d && b>e)
return b;
else if (c>a && c>b && c>d && c>e)
return c;
else if (d>a && d>b && d>c && d>e)
return d;
else
return e;
}
int minimumValue ( int a , int b , int c , int d , int e )
{
if (a<b && a<c && a<d && a<e)
return a;
else if (b<a && b<c && b<d && b<e)
return b;
else if (c<a && c<b && c<d && c<e)
return c;
else if (d<a && d<b && d<c && d<e)
return d;
else
return e;
}

thanks for your time
