Hey. i just wanted to know how to u graph a projectile motion in C++ using sine waves. im currently using the program Microsoft Visual C++. If u could help me start or tell me how would i go about graphing a projectile, i would be really appeciate it. thanx

you are in way over your head here...

First you need to know basic C++, to construct the functions and algorithms required to calculate the path. Then you'd need to be familiar with an API that can support drawing to the screen, such would be Win32, DX, OpenGL, MFC and other wrappers of the Win32 API.

i know the basics of C++ and i calculated the parth of a projectile. now i need to graph the projectile which is the part i need help in. but i am not fimilair with any of these names such as API oor the others. do u rekon u can give me a link or something that would give detailed information about these types (Win32, DX, OpenGL, MFC and other wrappers of the Win32 API). thanx for your reply.

hi. i need help graphing the projectile motion in C++. i need to do it as a sin wave. i got this far but i think the x axis and the y axis are on the opposite sides. can someone plz tell me how to flip this sin wave so it can look like a projectile motion. here is my code. thanx

#include <iostream.h>
#include <iomanip.h>
#include <math.h>
#include <cstdlib>

void main()
{
const float PI = 3.1416;
const int STEPS = 16;
const int SIZE = 15;
const char STAR = '*';
const char BLANK = ' ';
int step;
float angle;
int indent;

char again = 'n';

do
{
system("cls");

cout << " SINEWAVE SAMPLE PROGRAM\n\n";
cin.get();
angle = 0;
indent = 0;

for (step=0; step<=STEPS; step++)
{
angle = (PI) * step / STEPS;
indent = 5.5 + SIZE + SIZE * sin(angle);
cout << setiosflags(ios::showpoint|ios::fixed)
<<setprecision(2)
<< setw(6) << angle/PI << "pi";
for (int i = 1; i <= indent; i++)
cout << BLANK;
cout << STAR << "\n";
}
cout << "Angle\n(radians)\n\n";
cin.get();

system("cls");
cout << "Do you want to run the program again (y/n) ??? ";
cin >> again;
}
while ((again == 'y') || (again == 'Y'));
return;
}

how can can simulate your code in a vertical motion? a ball from the ground..
