C++ \\ Newton's Laws of Motion

[SuSa]

Somewhere on:
http://www.uow.edu.au/~nabg/ABC/C6.pdf

"Write a program that uses Newton's laws of motion to calculate the speed and the
distance travelled by an object undergoing uniform acceleration. The program is to take
as input the mass, and initial velocity of an object, and the constant force applied and
time period to be considered. The program is to calculate the acceleration and then use
this value to calculate the distance travelled and final velocity at the end of the specified
time period."

Program I ended up writing:

Did I do it right? >.< I don't think I needed to include math.h

EDIT:
I did it the hard way. Turns out the answer was:

double s, u, a, t;
cout << "Enter initial velocity, acceleration, and time : ";
cin >> u >> a >> t;
s = u*t + 0.5*a*t*t;
cout << "Distance travelled " << s << endl;

lol thats pretty basic. The only thing you need to know, is newton's laws of motion. The rest is just an easy use of the standard c++ iostream library with cout and cin functions.

I like the old way tho. printf and scanf makes more much sense for me.

EDIT: if that's all of your code that is inside the main function, I say nope, you don't need the math header, just iostream.

I'm been coding in c++ for all of a matter of...... that day. <_< I then went on vacation and just got back.

Thought so. Didn't know the math header.

/next little program will be using a function. wee... simple stuff still but I need to learn it

for what do you need/want to learn C++?
