Passing result of one routine to another

[kamathmahendra]

Dear all

I'm writing a C++ program including 2 routines where I need to pass result of one routine to another for further calculations. How to I proceed with it? Please help...
My program1.C is like this -

//program1:

using namespace std;

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

int main ()
{
float x1, y1, z1, x2, y2, z2, xa, ya, za, theta, omega;

cout << "\nEnter Pt.1 X value\t";
cin >> x1;
cout << "\nEnter Pt.1 Y value\t";
cin >> y1;
cout << "\nEnter Pt.1 Z value\t";
cin >> z1;

cout << "\nEnter Pt. 2 X value\t";
cin >> x2;
cout << "\nEnter Pt.2 Y value\t";
cin >> y2;
cout << "\nEnter Pt.2 Z value\t";
cin >> z2;

xa = fabs(xr-xs); ya = fabs(yr-ys); za = fabs(zr-zs);
theta = atan(za/(sqrt(xa*xa + ya*ya))); 
omega = atan(ya/xa);

cout << "\ntheta = "<< theta;
cout << "\nomega = "<< omega;
cout << "\n\n";

(theta, omega) = program2();  // don't know if this is correct
}

When does your instructor say this assignment is due?

[kamathmahendra]

This is not an assignment. I'm new to C++ and Unix and trying out to develop a software. Kindly reply if you have a solution.

Its easier to make fun than to help.

do you mean something like this?

void func(int&, int&);

void func2(void (*)(int&, int&), int&, int&);

where func2 contains func prototype as a parameter.

or

int func(int x);

int func2(int x);

int y = func2(func(45));

wje asked that question because this does sound like a homework assignment, and you gave us no context in which to work. It is against the forum rules to put up homework assignments, hence the question.

So then, I'm afraid I don't understand what you're trying to do. You have a function called program2, apparently. Are you trying to pass theta and omega into program2? What does program2 do? What parameters does it take?

Precisely.

Welcome! I hope we can help you. Cabhan has started you out with a question for which I'd like the answer as well. :)
