Need help in correcting actual codes.  Errors returned from unix.  Please advise.  Del

Code 1:

// ver_7.cpp

#include <iostream>

using namespace std;

int main()
{
   point p_array[2];
   double distance;
   inputFun(p_array);
   distance = calculate_fun(p_array);
   printFun(distance);

   return 0;

}

Code 2:

// ver_8.cpp

#include <iostream>

using namespace std;

int main()
{
   DistanceOfPoints obj_1;
   obj_1.inputFun();
   obj_1.calculateFun();
   obj_1.printFun();

   return 0;
}

Code 3:

// ver_6.cpp

#include <iostream>

using namespace std;

void input_fun(double p_array[2][3]);
double calculate_fun(double p_array[2][3]);
void print_fun(double distance);

int main() {

   double p_array[2][3];
   double distance;

   input_fun(p_array);
   distance = calculate_fun(p_array);
   print_fun(distance);

   return 0;

}

void input_fun(double p_array[2][3]) {

   for(int i = 0; i <= 1; i++)
       for(int j = 0; j <= 2)
            cin >> p_array[i][j];

}

double calculate_fun(double p_array[2][3]) {

   double distance;
     
   distance =

   return distance;

}

void print_fun(double distance) {

   cout << "distance = " << distance << endl;

}

code 4:

// ver5.cpp

#include <iostream>
#include <cmath>

using namespace std;

void input fun(p_array);
double calculate fun(p_array);

int main() {


   double p_array[2][3]; // data structure, memory location for your variable
   double d;

   input fun(p_array);
   calculate fun(p_array);
   print fun(double d);

   d = calculation function;

   print fun(d);

   return 0;

}

edelossantos,

Are you trying to make one executable binary from multiple source files or 4 independent binaries?

I'm, guessing the former but just to be sure..

These are codes that have been given to me for correction.  There are 4 independent files.  I gravely need help in the correction of the actual codes.  In other words, the codes need to be corrected.  Please advise.
