Question

anybody knows c++ programming?

Answer 1

i took a university class on basic c++. maybe i can help.

always best to post question right away rather then ask for future help ^_^

Answer 2

i'm trying to to plot a graph for polynomial equation;
here is the program; idk why but i keep getting syntax error on return value.
#include<iostream>
#include<math.h>
using namespace std;

double a, b, c, x, y, xs=.1, ys=4;
double cy(double x); return a*(x*x)+(b*x)+c;

void main(){

cout<<"Enter three coefficent for polynomial function: ";
cin>>a>>b>>c;
for (int i = 0; i<40; i++)
x=xs*i; y=cy(x); cout<<x<<" "<<y<<endl;
for(int s = 0; s<y*ys+40; s++)
cout <<" "; cout<<"-"<<endl;

system("pause");

}

Answer 3

nvm i was able to fix up the return syntax error, but can yall help me plot a curve graph with any polynomial degree. so far i used only two degrees
