Computer: Language: Compiler: C++: Include: Class: How to?

---

Include your classes in e.g. (one or more) .h files
(without a main class).

---

In the main file put the main() routine,
where you call your classes (e.g. by initializing
an object of that class).

---

===

Steps: Overview:

 1. -Create 2 files

 2. -Create one or more sub files containing 1 or more classes

     1. -Save this file as <your filename>.h

         1. -E.g. save this as

                   myClass1.h

--- cut here: begin --------------------------------------------------

// library: array: minimum [kn, amv, tu, 21-02-2006 13:42:15]
class arrayC {
 public:
  double FNArrayMinimum( double t[], int minI, int maxI );
};
//
double arrayC::FNArrayMinimum( double t[], int minI, int maxI ) {
 double min = t[ minI ];
 //
 for ( int I = minI; I <= maxI; I++ ) {
  if ( min > t[ I ] ) {
   min = t[ I ];
  }
 }
 return( min );
}

--- cut here: end ----------------------------------------------------

 3. -Create main file

     1. -Call <your filename>.h between double quotes

--- cut here: begin --------------------------------------------------

// library: array: minimum [kn, amv, tu, 21-02-2006 13:42:15]
#include <iostream.h>
#include "myClass1.h"
//
main() {
 arrayC arrayO;
 //
 double t[] = { 1, 2, 3, 4, 5, 6, 7 };
 //
cout << "minimum = ";
cout << arrayO.FNArrayMinimum( t, 0, 6 );
cout << endl;
}

--- cut here: end ----------------------------------------------------

 4. -Compile and run this main file

 5. -That will show (in this example)

      minimum = 1
