Answer to Question #14576 in Action Script | Flash | Flex | ColdFusion for enjila

Question #14576
Write a C++ program with a nested loop structure that displays the sinusoidal curve f(α)=35sin() in ‘*’ for f(α) ≥ 0 and in ‘o’ for f(α) < 0 as shown in Fig. 1. The curve starts at =0, and the sampling step-size of the curve is 0.1π. You program should plot at least a full cycle (0 ≤  ≤ 2π)
Expert's answer
#include <math.h>
#include<iostream>
using namespace std;


int main()
{
& float a,b,c,d,x,pi=3.141592;
int i,j,k;
cout<<"The sin curve is plotted below:& \n\n";

cout<<"-35 & 0 & 35\n";
& cout<<"-------------------------------------------------------------------------->";
& for (i=0;i<22;i++){
x=35*sin(2*pi*i/20);
& // cout<<x<<"\n";
& k=(int)x;
& //cout<<k<<"\n";
& for (j=-35;j<36;j++){
& if(k==j && k>0)
& cout<<"*";
& else{
if(k==j && k<0)
& cout<<"o";
& else&
& cout<<" ";
& }
& }
& cout<<"\n";
}
