Stepenovanje u Dev C++

hvala na pomoći

Sad sam napisao prog. da računa po toj formuli, sad treba još da računa i po drugoj formuli, sa istim parametrima



#include <cstdlib>
#include <iostream>
#include <cmath>


using namespace std;

int main()
{
//Definiranje ulaznih velicina

float focallength,nearlimit,farlimit,total,circleofconfusion;


float fstop,subjectdistance;

//Geometrijski i maseni podaci

cout << "Unesite F STOP:" << endl;
cin >> fstop;
cout << endl;
cout << "Unesite SUBJECT DISTANCE: s=" << endl;
cin >> subjectdistance;
cout << endl;

//konstante

circleofconfusion=0.019;
focallength=100;

//formula

farlimit = (subjectdistance* (((focallength*focallength)/(fstop*circleofconfusion))+focallength)-focallength)/(((focallength*focallength)/(fstop*circleofconfusion)+focallength)-subjectdistance);
cout << " Far limit je : " << endl;
cout << farlimit;
cout << endl;



Dn = (s*(((f*f)/(N*c))+f)-f)/(((f*f)/(N*c)+f)-s)

to je ta druga formula , dali mogu napisat i nju u program




system ("PAUSE");
return 0;

}

Ako sam te dobro razumio, ti hoćeš da ti zadatak riješi i po drugoj formuli, ali rješenje ti je isto, ako si to htjeo, evo rješenja:

Code:

#include <cstdlib>
#include <iostream>
#include <cmath>
using namespace std;

int main()
{
//Definiranje ulaznih velicina

float focallength,nearlimit,farlimit,total,circleofconfusion;


float fstop,subjectdistance;

//Geometrijski i maseni podaci

cout << "Unesite F STOP:" << endl;
cin >> fstop;
cout << endl;
cout << "Unesite SUBJECT DISTANCE: s=" << endl;
cin >> subjectdistance;
cout << endl;

//konstante

circleofconfusion=0.019;
focallength=100;

//formula

farlimit = (subjectdistance* (((focallength*focallength)/(fstop*circleofconfusion))+focallength)-focallength)/(((focallength*focallength)/(fstop*circleofconfusion)+focallength)-subjectdistance);
cout << " Far limit je : ";
cout << farlimit;
cout << endl;


// *novi dio, za rjesavanje po drugoj formuli
cout<<endl;

float Dn, s, f, N, c;
s = subjectdistance;
N = fstop;
c = circleofconfusion;
f = focallength;

Dn = (s*(((f*f)/(N*c))+f)-f)/(((f*f)/(N*c)+f)-s);

cout<<"Rjesenje po drugoj formuli: "<<Dn<<endl<<endl;
// *kraj novog dijela


system ("PAUSE");
return 0;

}
