program help

[Geminias]

hey, i'm a noob having some trouble with this program. Won't compile and i don't understand the compiler's hints. If anyone could give me some pointers on what is wrong please do so.



Syntax = C++

code:

#include <iostream> #include <windows.h> #include <math.h> using namespace std; float quadrant1y (float s, float t) {       float yaxis;       yaxis = sin*s*t;             return (yaxis); }   float quadrant1x (float x, float y) {       float xaxis;             xaxis = cos*x*y;             return (xaxis); } int main () { cout << "This program will resolve vectors into their components.\n"; cout << "Just follow the instructions. /n"; sleep (1000); cout << "Enter the displacement in km"; cin >> displacement; cout << "input the angle."; cin >> angle; if (0 <= angle <=90) {    quadrant1x (angle, displacement)    quadrant1y (angle, displacement) }    cout << "the x axis is: " << quadrant1x << endl;    cout << "the y axis is: " << quadrant2y << endl;          return 0; }

Well, there are many things wrong with your code, but one stands out in particular. "sin" is a function. Why aren't you calling it as such?

code:

sin*s*t

[Geminias]

i thought it was more like an operand

[wtd]

Also, where is "displacement" declared?

code:

cin >> displacement;

I was going to write a nice big thing here but sicne I seem to have been beaten to it while writing it I'll just post some fixed code so you can see it working:

c++:

#include <iostream> #include <windows.h> #include <math.h> float quadrant1y (float s, float t) {       return sin(s*t); }   float quadrant1x (float x, float y) {       return cos(x*y); } int main () { float displacement; float angle; cout << "This program will resolve vectors into their components.\n"; cout << "Just follow the instructions. /n"; sleep (1000); cout << "Enter the displacement in km"; cin >> displacement; cout << "input the angle."; cin >> angle; if (0 <= angle <=90) {    cout << "the x axis is: " << quadrant1x(angle, displacement) << endl;    cout << "the y axis is: " << quadrant2y(angle, displacement) << endl; } return 0; }

thanks guys. But one question.

you put "sin(s*t)"

is that the same as "sin(s) * (t)" ?

because it is not the same thing on a calculator.

No.

You have the function name, then parentheses. Inside the parentheses are any argument(s) to the function.

In this case the argument is "s * t".

Nice new sig, wtd

You were also missing some ';''s from the end of some lines, try to check that first if you get some errors (which should easily tell you that this is the problem).
