Please note, that this is not a homework site. We won't do your homework for you. However we are always willing to help solve problems you encountered, correct mistakes you made in your code and answer your questions.

We didn't see your attemts to solve this problem youself and so we cannot correct mistakes you didn't made and answer questions you didn't ask. To get help you should do something yourself and get real problems with something. If your problem is "I don't understand a thing", then you should go back to basics and study again. As it is impossible to find deriviative of function without knowledge in ariphmetics, you cannot do more complex tasks in programming without clear understanding of basics

this is what i did but it doesnt run


#include "stdafx.h"
#include <iostream>
using namespace std;
#define del_array
int _tmain(int argc, _TCHAR* argv[])
{
int z[40];
int i,imin,n;
float k,S,min;

cout<<"n="; cin>>n;
cout<< "please enter "<<n<<" intergers:" <<endl;
for(int i=0;i<n;i++)
{
cin>>z[i];
}
cout<< "\n values in array are now:";
for(i=0;i<n;i++)cout <<" "<<z[i];
cout <<endl;// for inputing of array

for(k=i=0;i<n;i++)
if(z[i]>0)
{k++;
if (k==1)
{min=z[i];imin=i;}
else
if (z[i]<min)
{min=z[i];imin=i;}}
cout<<"min="<<min<<"\n"<<endl;
{
int *z;int n,i;
cout<<"n=";cin>>n;
z=new int[n];
cout<<"Array z/n";
for(i=0;i<n;i++)
cin>>z[i];
for(i=0;i<n;)
if(z[i]>0);del_array(z,i&n)else i++;
if(z[i]>0) n=del_array(z,i,n)else i++;
cout<<"output array z\n";
for(i=0;i<n;i++)
cout<<z[i]<<"t";
}
return 0;
}

So you missed ; before else in two lines and got an extra ; directly after if condition.

I think error messages are descriptive enough
